Not sure the point of this post really. Just a place to air my thoughts. I've very kind in laws so I'm very lucky but I often find them too much since having a baby a year ago.
When DC was born, in laws have helped out, taking DC for a walk, cooking us a few meals. All great. We're very grateful.
They started offering to have DC for an afternoon or day to give me a break. I politely declined, said DC is too little, breastfeeding, cluster feeding, would love this when DC is older etc etc. Got to a point where they kept offering and I had to keep repeating the above, I actually counted 9 times in one week between the two of them! I felt it became less of an offer of help and more them wanting more time with DC. I get it, they love their grandchild but it was too much
DC then went through a clingy stage with lots of crying, in laws messaged asking to have them for a few hours. We politely declined but said they were welcome to visit and maybe take DC for a walk. They complained they weren't able to bond with DC properly if just pushing them in the pram but would come over. We didn't acknowledge that part of their message to avoid a spat over text but we found it overbearing and they must have realised they were being silly as they didn't bring it up in person. My whole maternity I had a gut feeling they felt they didn't see DC enough even though we saw them twice a week.
There's the excessive buying. DC has plenty clothes and toys but despite saying we don't need anything more they keep getting things we've already got. Sure it's a nice problem to have but I hate waste, I feel I'm not listened to and sometimes I wonder whether they think the stuff we have got isn't good enough somehow (pretty sure that's not the case, just think they can't resist buying things) At Christmas they got twice as much stuff as we did for DC. DC has 20 cuddly's as they keep buying them! We're getting in laws to keep some toys and clothes at theirs now.
Every day we get a message asking how DC is. If we don't reply the other will ask. At every stage we've gone through with DC they've wanted to know every detail but then don't listen. So many comments about teething, weaning, sleeping, breastfeeding. I tell the bare minimum now so I don't have to explain things over and over. I can't remember how many times I heard them say "DC is feeding again! Surely they can't still be hungry! 
I just hoped it would calm down once the initial excitement wore off. We're super grateful for their help and they've not done anything wrong but I often find it too much. I can't exactly say stop being so excited to have a grandchild so I've come here to let my thoughts out. Even if no one responds, I feel a bit better getting it out my head!
