How Is Infant Development Impacted When the Mother Has BPD?

Pamela holds a Bachelor's of Arts in Sociology and Psychology and Master's in Public Health. She was raised by a mother with BPD.

Intrusive insensitivity is often seen in the adult relationships of those with BPD as well.

Can a Mother With Borderline Personality Disorder Influence Infant Development?

From birth to age one, babies experience a monumental number of milestones. During their first year of life, babies develop a bond with their parents or other caregivers. It is during this time that babies learn to love and trust, which is dependent on the way parents interact with, hold, play, and cuddle their infants. Developing trust during the first year of life is a key milestone for later social and emotional development: It sets the stage for how a baby will interact with others as they grow.

When babies do not develop a bond with their parents or other caregivers and do not learn to trust that the parent will respond to their needs, lifelong complications can ensue. Research has examined the effect of mothers with borderline personality disorder on their infants. Science has discovered that, even in this earliest stage of development, a mother's borderline personality disorder (BPD) influences infant development.

Mothers with BPD are inconsistent in fulfilling their infant's needs because they cannot interpret those needs. This is similar to the problem that women with BPD have in adult relationships when interpreting the needs of their friends or significant others. Furthermore, mothers with BPD report a myriad of feelings when they become a mother: estranged, anxious, overwhelmed, and angry.

Although it is important to conduct research on how a mother with BPD may influence the early development of her infant, little research has been conducted to date. This article will examine three studies that all built on the scientific evidence provided in the first study discussed.

Why Does This Happen?

There are a myriad of symptoms associated with BPD, including emotional instability and extreme difficulty with interpersonal relationships. In general, these symptoms are thought of in terms of how a woman with BPD interacts with another adult. However, researchers were curious if mothers with BPD showed the same emotional instability and difficulty with interpersonal relationships with their own infants.

In fact, researchers demonstrated that concept in a study with mothers with BPD and their two-month-old infants. Compared to mothers who did not have BPD, mothers with BPD demonstrated the characteristic intrusive intensity often seen in their adult relationships.

Mothers with BPD are less sensitive to a baby's needs.

Interpersonal Relations and Development in Infants

Another group of researchers followed up on this finding with their own study. The second group of researchers thought the way mothers with BPD interacted with their infants would influence the infant's development of interpersonal relationships as well as influencing the overall development of the infant. These scientists hypothesized that, even as early as the baby's first birthday, an infant who had a mother with BPD would have already developed problems related to maintaining emotional equilibrium during stressful interpersonal encounters.

To test their hypothesis, the researchers included mothers with BPD and their infants as well as mothers without BPD and their infants. All babies were 12 months old. All mothers and babies participated in three activities:

  1. First, the babies interacted with a "still-faced" stranger.
  2. Then, babies participated in the "Strange Situation."
  3. Finally, mothers and babies played together with toys.

The Outcomes

The babies of mothers with BPD had negative outcomes compared to the babies with non-BPD mothers:

  • When interacting with a "still-faced" stranger, babies of mothers with BPD were less available for positive engagement, and they received decreased ratings for behavior organization and mood state.
  • While taking part in the Strange Situation, most babies with mothers with BPD were categorized as having behavioral disorganization.
  • Mothers with BPD were shown to be intrusively insensitive when playing with toys with their babies.

How Do Mothers With BPD Perceive Their Parenting?

One additional study was conducted to examine mothers with BPD and their relationship with their infants. Scientists asked mothers with and without BPD to participate in their study. All their children were between three months and 36 months old.

  1. First, all mothers completed questionnaires that asked mothers about their own perceptions of their parenting.
  2. Then, mother and infant pairs were observed, and their interactions were rated.

The Outcomes

Compared to controls (controls are mothers without BPD), there were several important findings for mothers with BPD:

  • When reporting on their own parenting, mothers with BPD said they were less satisfied, less competent, and experienced more distress related to motherhood.
  • These mothers demonstrated less structure when interacting with their babies.
  • They were also less sensitive to their baby's needs, were less attentive to their babies, and seemed to be less interested and eager to interact with their babies.

Did you mean babies who grow up with BPD mothers? I think we can all overcome our upbringing to some degree. It will be easier for some and harder for others. People, especially women, with a first degree relative with BPD are more likely to develop BPD themselves. For those individuals, recovery would be more difficult (in my opinion) than for someone who did not develop BDP.

Here is a link to another article I have written about how NPD and BPD mothers influence early childhood development (ages 3 to 7). That might also be helpful for you to process your experiences.

This is interesting to me as I'm starting to unpack my own repressed early emotional trauma now at age 51! Do you believe babies who grow up with BPD can overcome this early deficit?
