Since having my DD in May, my PIL have visited her on average once a fortnight for about an hour. I was in hospital for 6 days after having her and they visited once although we told them we were happy for them to visit everyday. They live about 40 minutes away and usually come to us, although we have also visited them at their house and these visits are usually longer (2.5 - 3 hours). However, recently they have gone 4 weeks without seeing her (even though we offered to visit them). When they visit, they interact with her well but don't deal with crying/nappies etc (not that I expect them to). As soon as she needs a feed or looks tired, they leave - I explain that I will take her to feed upstairs and bring her back down, but they insist on leaving. They are also very reluctant to pass her to me when they are here, they always pass her to my husband - when she was clearly hungry the last time they visited, I had to take her from my FIL's arms in order to be able to feed her.
Recently, they have been asking and offering to baby-sit her so that we can go out, My DH's birthday is coming up and they have said that they would look after her if we wanted to go out for a meal. However, I really don't feel comfortable leaving her with them - she is not familiar with them and they don't know her signs (for example, I have to explain to my FIL that when she rubbed her eyes it meant that she was tired). AIBU to not want to leave her with them? If not, how do I explain this to my husband/them?
For full disclosure - My parents have looked after her 3 times since she was born, although they see her much more frequently. I only really trust my mother with her at the moment.
