DD is 4 and has autism. She has lots of sensory issues and I spend a lot of time trying to help her with these. Six months ago she'd struggle to even leave the house because she was so terrified of the rain, wind, dogs,cars coming towards her etc. She would fall over if someone was walking behind us. She ate three foods and only if hand fed. Now, when DP is at work she will eat around 12 foods and feed herself and is very proud of herself for doing so. She will walk outside holding my hand and cope with reassurance and preparation before journeys.
However, when DP is off work, he will carry her or put her in the pushchair at all times - even from the car to the shop/house. He does not encourage her to walk at all. She hides away in the bottom of the double pushchair she shares with her sister. He starts hand feeding her before even giving her a chance to do it herself. So today was his first day back at work after ten says annual leave and DD wouldn't walk anywhere or feed herself. It will take ages and a lot of upset to get DD back to the stage she was at, then DP will undo all DDs hard work again.
Aibu to think DD needs to be able to do these things and that he's undermining me and making things harder for DD in the long run?
