I Have two children. A 6 year old and a 11 week old baby. My mums always been a bit of a takeover when it came to my eldest. But since my second she's got worse. She constantly undermines me. She'll tell my eldest yes , when I've said no and has a massive smirk on her face doing so. If my eldest hurts themselves she tries shoving me out of the way too soothe my 6 year old. With the newborn she tried to give him chocolate the other day and I said no she argued back and forth for a few minutes then gave in , but said you wait until Christmas Day I'll be sneaking the baby some! With the newborn she'll snatch them of the dad whilst he's doing a feed or barge him out the way if he's trying to do a nappy change cause she wants to do it. She looks at my partner funny when he's holding the newborn and make remarks like " they don't like that stop it!" Or I wouldn't have done that too one of mine. Me and my OH are dreading christmas at my mums because of this , but my mum is one of them you can't say she's annoying you because she takes it personally and acts the victim and the water works will start. I just don't know how to basically say stop undermining me without a massive confrontation :(
