Am I being too sensitive?

So my mother in law keeps making comments about my daughter. Everytime we go to her house she insists on bathing my daughter and brushing her teeth. And whenever we are with her she makes comments about my daughter needing a nappy change or needing a drink. But she doesnt say it to me, she says things to her daughter (my daughters Auntie who is also younger than me) 'Oh I think DD needs a nappy change' or 'Could you do her nappy' or 'Do you think DD would like a drink'. I feel like it is rude that she never says it to me or my husband. If she feels our daughter needs something then she should say it to me or my husband, right? I just feel like she thinks we dont look after her. We have also taken an approach where when DD falls over we dont make a fuss. She has never cried when she has done something unless it really does hurt. But my MIL makes such a fuss and then recounts the episode to me, even though I saw the whole thing, but she says it in a way that makes me feel so irresponsible i.e. 'Did you see that, she almost hit her head'... In my head Im like 'Yeah but she didnt and she didnt make a fuss sooooo...??!' My daughter is almost 2 and I kinda feel like we have kept her alive that long so we must be doing something right 😂 And with her making constant comments about napph changes etc, my daughter has never had nappy rash or anything so it isnt like we arent changing her enough! Im just fed up of feeling like she thinks Im a terrible mother! It really undermines my confidence. My husband has spoken to her about how we dont like people making comments like that and that we look after our daughter and it is pur responsibility. He tried to make it general so it wasnt like having a go at her and things had got beyter but now she has started again. Am I being oversensitive? Or do you think she is sticking her nose in abit too much? I do appreciate her comcern, but I can look after my daughter and make the choices that I feel are best for her. I am 22 and my husband is 24 so I feel like she still views us as kids but we have been married over 4 years, we work full time and have lots of responsibilities that most people our age dont have. Anyways, sorry for the essay but I would really appreciate some advise! Thanks!
