DD (8yo) has a neurological condition which means that she constant rubs her head on her pillow all night, every night. This means that her hair is very tangled every morning and she needs a lot of help, with spray oils etc to brush it properly every day. She can't do it herself and it is a real task even for me.
The last weekend she spent with her dad (my ExH) she came back with really matted hair and I reminded him that she needs help to brush it, or at least "check" it for her when she has finished.
He brought her back last night, after having her for five days over Christmas. He has not helped her to brush her hair once during this time. It was almost in dreadlocks and it took over an hour, a bottle of conditioner and lots of distress to sort her hair out.
AIBU to think that this is very neglectful on his part? She has had fun over Christmas with him and I know I have residual anger towards him so I'm not sure how upset it is reasonable to be about this.
DD also has MH issues and low self esteem and I think that makes this worse.
