My(32M) wife(30F) had our first daughter 6 months ago and shes a beautiful down syndrome baby that we love so much.

So recently we just had a family event at my aunt's house and all the relatives were there and that was the first time that everyone got to meet our baby.

As I was talking to my aunt about our baby, my cousin's husband came and said my baby was ugly and made a face when he watched her. So I stood up and said "Well at least she wasn't born an illigitimate child and I didn't destroy my life by being a teen parent like you."

For context we're muslims and he and my cousin weren't married when they had their child and they're both still 19.

So AITAH?
