AITA for “parentifying” my foster daughter?

What happens when a very young child only trusts one person to prepare their food, and that person is their older sibling? In families with trauma, small routines like meal prep can become lifelines of safety and comfort.

This story centers on a foster parent caring for three siblings who narrowly escaped separation. The youngest, a 4-year-old, refuses food unless her 13-year-old sister makes it. When the parent asks the teen to help, a friend labels it “parentifying.” The post explores the delicate balance between meeting a child’s immediate needs and protecting everyone from unfair burdens.

‘AITA for “parentifying” my foster daughter?’

The post begins with the family background and the specific challenge with the youngest child’s eating habits.

The situation came to a head during a dinner with friends, leading to the accusation of parentifying.

This situation highlights the common challenges in foster care, where children carry deep trauma responses into new homes. The 4-year-old’s extreme pickiness centers on food prepared by her sister, likely because Diana represents safety and consistency after loss and instability. The parent’s request for help stems from a desire to ensure the child eats, rather than force a confrontation that could worsen trust issues.

The 13-year-old may have taken on caregiver roles long before entering foster care, a pattern often seen in sibling groups facing hardship. Her willingness to help suggests she feels secure doing so, but the risk lies in unintentionally reinforcing that role if it continues indefinitely. The friend’s strong reaction reflects valid concern about parentification, yet the current limited involvement appears more like sibling support than full caregiving.

Trauma-informed parenting expert Dr. Karyn Purvis emphasized that “for children from hard places, connection before correction is essential” (The Connected Child). Here, preserving the sister’s role as a secure figure builds trust, which can later open the door for the parent to step in more fully.

To move forward gently, talk openly with the 13-year-old about her feelings and affirm that this help is temporary. Work with a trauma-informed therapist to gradually expand food acceptance. Involve all three kids in simple, fun food prep together to strengthen bonds and ease transitions without pressure.

Here’s what people had to say to OP:

Social media responses overwhelmingly supported the foster parent, viewing the request as a practical, temporary solution rooted in understanding trauma. Most emphasized that limited sibling help differs greatly from true parentification. A small number urged addressing the dynamic sooner through therapy.

The majority of commenters defended the approach and praised the empathy shown toward the children’s needs.

Others stressed the trauma context and advised patience while seeking professional support.

A few commenters felt the dynamic needed addressing sooner to avoid long-term issues.

This experience reveals how deeply trauma can shape everyday routines, especially around food and security. By allowing the older sister to help in a limited way, the foster parent prioritizes the children’s immediate emotional safety while building trust. The key lies in open communication, professional guidance, and gradual change—ensuring no child carries an unfair load while healing happens.
