Mother in law

Sorry for long post need a bit of a rant and some opinions if I am over reacting. Guys I need other opinions rather than people I am close with. Me and my partner had a baby 8 months ago and when I was pregnant I said to him I want me and you to do everything with them before we do it with other people. Little back story I grew up with parents who couldn’t drive so never experienced anything and I 100% was not having that for my child however, my partner is so close with his mum as he is the only child and it has always been them 2 so he experienced a lot. Am I wrong for saying that if we go to the aquarium, zoo, days out it will be us as a family first? On another note, my partner wants his mum to be there for everything rather than it just be me, him and the baby and when I say why can’t it just be us 3 he goes a little moody and argumentative saying why can’t my mam come to anything. It just feels like he is prioritising his mam than his own family and what makes me say this also is he asked me earlier how would I feel if he took his mam out for Mother’s Day my response “are you taking the piss”, I responding like this because I am his child’s mother. I don’t know it just seem like he doesn’t respect me or priorise me but he does with his mam.
