Before you get the wrong idea, my son is 3 mths old. But the issue is I don't agree with children sleeping in their parents bed (unless poorly and need a cuddle, but even then probably returned to their own bed afterwards), so why should it be different for MIL?
The background is that MIL already has a granddaughter. For the first couple of years of her life she lived with MIL, but since MIL's DD moved out with DG (then aged 2), DG has slept with MIL in her bed when MIL babysits.
DG has a suitable bed in the spare room, but MIL sends FIL to sleep there, so she can have DG in her bed. When I recently asked why she has DG sleep with her, she said 'oh, I think it started as we have a TV in our room', and didn't add anything further. And when I said 'what a shame about FIL being sent to the other room', she said he didn't mind. Its very clear that she wants DG there as she wants to be close to her.
Thats fine for them, but recently, she said to my DS 'soon nanny will get to babysit you and you can come sleep in nanny's bed'.
I won't be having my DS sleep in our bed, as I think children should have their own bed and don't want bad habits to set in, so I don't see why it should be different for MIL.
At the moment its easy for me to say my DS is too young, making it dangerous, especially as MIL smokes, but she says she is giving up and I imagine she will expect my DS to stay in her bed when he is past the danger stage.
Am i the only one to think this is weird and wrong, especially without asking me? Or should I just chill out and let nanny do what she wants as it wouldn't be very often.
