AITA for not engaging with my sister during my pregnancy?

A 28-year-old woman, finally pregnant after years of infertility struggles, has gone low-contact with her 30-year-old sister. The rift started when she couldn’t provide free emergency childcare for her sister’s kids—disrupting her licensed in-home daycare business.

The sister responded by blocking her for eight months, withholding access to the nieces, and only reappearing with congratulations once the pregnancy was announced. Now expecting involvement in the pregnancy journey, the sister is upset at the continued distance.

An update revealed deeper hurt:

Pregnancy heightens emotional sensitivity, making toxic dynamics especially draining. Withholding grandchildren as punishment—weaponizing access—is a common but harmful control tactic in dysfunctional families, often rooted in unresolved resentment rather than the triggering event.

Boundaries during major life transitions protect mental health. Low-contact allows space without permanent rupture, giving time for reflection. Family therapist Nedra Glover Tawwab notes in Set Boundaries, Find Peace that “people who punish with silence expect you to chase them”—refusing to engage breaks that cycle.

Reconciliation requires accountability: genuine apology, changed behavior, and respect for limits. Without it, distance preserves peace for the new family unit.

Professional support—like prenatal counseling—helps process grief over lost relationships while focusing on positive ones ahead.

This pregnancy boundary battle has everyone debating silent treatments, weaponized kids, and when enough is truly enough in family ties.

Where do you stand on using children as leverage in adult conflicts? If someone ghosts you for months over a perceived slight, can the relationship ever fully recover—or does trust stay broken?
