Postnatal anxiety issues

My 4 month old daughter is the only grandchild on both sides of the family. I feel the pressure on regular visits as well as excessive grand-parenting, I have felt Uncomfortable with it quite often. I now have postnatal anxiety and I feel like this has contributed to it 🙁.

I had a conversation today with my OH about our families involvement and he admitted that his mother is very likely going to take over during holidays, Christmas etc.... I’m just worried that I’m going to miss out on precious moments with my daughter in the future 😔. They recently spoke about us all going to Disney, amongst other holidays when she’s older, and my OH also admitted that she’s very likely going to take over then too... I understand it’s their only grandchild but she’s also my daughter and they haven’t quite grasped that they need to share the time they have with her, with me too. My anxiety is also sky high and this has been on my mind a long time...

Does anyone have any words of advice?
