Just venting: ex keeps texting me about non-emergency stuff during my custody time

"did you pack jake's soccer stuff?" "remember his asthma inhaler" "he needs a haircut soon" "btw his teacher wants to meet about grades"

All during the times he's with me. I KNOW my kid. I've been doing this for 5 years. I don't need play-by-play instructions. But if I don't respond right away she acts like I'm being difficult. Just let me parent without the constant updates challenge (impossible)
