Mum keeps wishing my baby’s development stages away

I am living the same problem! Only that due to my circumstances, im having to live in my parents house. Nothing I do is to her standard. She has been so disrespectful and its been mentally draining living here.

Express yourself on how she makes you feel when she says those comments. If she doesn’t respect you, go longer stretches without communicating.

Honestly, I'd cut contact. You don't need a negative ninny in your life

My mom is like this it’s soooooo annoying and irritating

Her memory of when her children hit these milestones is likely a bit truncated. It's probably been a while and I think older parents memories are often a bit off when it comes to things like this. Just mention what the actual medical standards for these milestones are when she brings them up. Every time. She will likely get tired of hearing it from you and relax about it.

Speak up, if you wanna save the relationship but if she doesn’t abide by the rules you set for your kid, down to how she speaks to them, cut contact.

Wow..I would tell her off. Because after that it will be about reading, school or sport results,... Your kid doesn't need that kind of pressure.
