Eyes needed please!

Okay so I'm 22 weeks pregnant and my partner (my child's father) has already started making rules about what I do and when I do things with my baby and I am okay with most of them, but, him and my dad don't get along and he's trying to tell me that our child is not going anywhere near my dad which I don't think is his choice at all, I told him I'd be taking him to see my dad anyway and he keeps talking about how he's going to make it as awkward as possible for me and my child to travel to England to see my dad, but my question is.. If my partner is on the birth certificate, does that mean I would need permission from him to take my baby from Scotland to England for a week to see my dad?

UPDATE:

A couple of days ago I decided I needed a break so I went to England for a few days to visit my dad and other family, he wasn't happy about this so he had girls sleep over in my house, not only did he have them in the house but he actually text me telling me they were there and then ignored me until evening time the next day, when he finally got in touch he refused to tell me why he had these girls sleeping over so I got the bus back to my house. Now HE is trying to break up with ME!! I'm so upset about it and I know it's the right thing for me and my son but I can't can't handle the idea of being a single mum at the age of 21!! Why am I so weak? Why can't I just let him do me the favour of leaving me? 😭
