This is not a MIL bashing thread as she is a nice woman on the whole, she's just a bit "enthusiastic" about DS but he is PFG so I can sort of see why.
Just for context, we didn't get any photos taken of DS when he was born last year but we want to do some professional photos to commemorate his 1st birthday in a few months time (of just him).
MIL randomly announced a few months ago that she wanted to "get some professional photos taken of DS" for their house. DH and I informed her that we were going to get some done for his birthday, and that obviously they would be for whoever wants a copy and that she was welcome to however many she liked. She went quiet and then someone changed the subject, I asked DH after they had gone if he thought she was annoyed, and he agreed but thought it was maybe because she was wanting to organise it rather than us. We forgot about it.
The subject hadn't come up again, until tonight, MiL, FiL and 2 SILs were over (both SILs still live at home so they are very involved), when MiL said "we want to do a photoshoot of DS so can we arrange some dates". DH reminded her that we were going to do something in a few months to which she said that she wanted to be in them, along with FIL and 2 SILs and that they wanted to "use their own ideas", which basically translates to "we don't want to do it on the same day you're doing it". My DH then said "so basically some family photos with our son but without us?" and she said yes!
I'm not really sure what to think; we are not going to ban our son from participating in their shoot if that's what she wants, it's sweet that they love him so much but it just feels a bit weird that they don't want us to feature in it? Or aibu? I genuinely don't know! Do grandparents/Siblings tend to want stuff like this?
