Researchers in Germany studied 119 mothers of babies aged 0–24 months with excessive crying, sleeping problems, or feeding difficulties. They wanted to understand why some mothers struggled to feel bonded to their babies, and what role the baby's temperament and parental stress played.
The findings were clear: mothers with the weakest bonds reported two things in common—significantly higher parenting stress, and babies with lower "effortful control." Effortful control is simply your baby's ability to calm themselves when upset. Babies who struggle to self-soothe exhaust their parents.
Stress makes it harder to understand your baby
The study found another important pattern: mothers experiencing bonding difficulties were less able to pause and think about what their baby was feeling. Researchers call this "mentalization"—the ability to reflect on your baby's emotions and needs. When you're exhausted by constant crying or feeding battles, this mental stepping back becomes nearly impossible. Your brain is in survival mode, not connection mode.
This is a stress response, not a failure of love
The research shows that bonding difficulties are a predictable result of combining a baby with poor self-regulation and an overwhelmed parent. This matters enormously: your feelings of distance or disconnection are not a sign you don't love your child. They're a sign your nervous system is genuinely depleted. In cultures where mothers are expected to manage difficult babies quietly and independently—common in Singapore and across Asia—this guilt can run especially deep. This study suggests that guilt is misplaced.
How to start reconnecting
- Name the stress aloud to your partner, a trusted friend, or healthcare provider; keeping it silent amplifies the overwhelm.
- Seek practical support that reduces parenting stress—whether family help, professional guidance for your baby's feeding or sleep, or reassurance from other parents facing the same challenge.
- Know that when your stress decreases and your baby's self-soothing improves, the bond typically strengthens naturally; you don't need to "fix" yourself.
