My partner and I aren't actually married but his mother is the grandmother to my 4 month old. When my partner is there she is lovely. She compliments me and my parenting and says how wonderful I am. When we are alone however she feels the need to make comments e.g. I should really try going back to work full time and that she isn't sure about my sister having our daughter when I do go back to work and she keeps trying to get me to replace some of my daughters feeds with water to 'make sure she is hydrated'. The main problem is how these comments are making me feel. I have opened up to my partner who can understand me being annoyed but thinks I blow it out of proportion. The other day my partner told me he and his mum had childcare covered but were just worried about wednesdays when I do go back to work... I'm sorry but I haven't arranged her childcare yet as I don't know how many days I'm going back. The thought of them planning this without even running it past me makes me so angry and upset. Please give any advice you can. I could just sit and cry because I can't seem to let it go over my head and I'm worried about how much this is going to affect my relationship with my partner and my time with our child on maternity leave. Is it me being overly sensitive?
