AITA for hiding baby food from my 6y niece?

A woman sharing a home with her sister-in-law, brother-in-law, and their 6-year-old niece found herself in an awkward spot after welcoming her own 9-month-old baby boy. With the family temporarily living together while their new house is built, jealousy surfaced as the niece began grabbing the baby’s store-bought snacks and yogurt from the shared pantry.

What makes the story more complicated is the adults’ habit of loudly commenting that the baby “eats double and better” than the niece whenever he has a snack. This seems to fuel the niece’s picky eating phase and her interest in the baby’s food, leaving the mom to hide supplies since her sister-in-law doesn’t replace what’s taken. The tension highlights the challenges of multigenerational living and differing parenting approaches under one roof.

‘AITA for hiding baby food from my 6y niece?’

Temporary living arrangements brought new family dynamics after the baby’s arrival.

Comparisons from the family intensified the niece’s interest in the baby’s food.

The mom took steps to protect her baby’s supplies due to lack of replacement.

This conflict stems from the stresses of shared households, where boundaries around resources and parenting styles often blur. The mother’s decision to hide food prioritizes her infant’s nutritional needs, especially since baby-specific items are formulated differently and can be costly. Opposing perspectives focus on empathy for the 6-year-old, who may simply like the taste or packaging while navigating jealousy toward the new baby.

Some see the comparisons as harmful, potentially worsening the niece’s eating habits or fostering resentment. However, the responsibility lies with the parents to address their child’s diet without relying on the host’s supplies. Broadly, this touches on entitlement in temporary living situations.

Guests, even family, should respect the homeowner’s property and replace what their child consumes. The loud comparisons also risk long-term emotional impact on both children. Clear communication about expectations could ease friction until the move-out, reinforcing that protecting an infant’s essentials isn’t selfish but necessary.

Take a look at the comments from fellow users:

Many users backed the mom, emphasizing that baby food belongs to her child and the guests should replace or control what their daughter takes.

Several commenters offered balanced advice, urging a conversation about harmful comparisons while supporting the food protection.

A few brought lighter or practical suggestions to ease the situation without blame.

In the end, the mom chose to safeguard her baby’s food amid unhelpful family comments and lack of replacement, with most agreeing she’s within her rights in her own home. The situation underscores how temporary cohabitation can strain relationships when boundaries aren’t clear.
