Troubles leaving child

Just came on here to rant because I’m just getting so frustrated.

I HATE leaving my baby with other people, he is four months old and I only leave him with his grandparents to look after him when I have no other choice. But it’s usually on for a couple of hours and I still just worry about him the whole time. (They do see him all the time but it’s when we’re there)

And I always only leave him during his awake times because I don’t like the thought of him sleeping somewhere where I can’t keep an eye on him.

I was meant to leave him my mil today to help my sister in law move houses. But it was only for a couple of hours and she said he can nap there and I said no because i don’t want to.

And then she went on saying she knows how to look after a baby. And I explained it’s nothing to do with her, I have anxiety and don’t feel comfortable doing that.

And she went on saying I have to get over it and he needs to get used to sleeping there and being with them without me there so his comfortable there especially for when I go back to work. (Which I’m not planning on going back to work anyway maybe only 10 hours a week when he is 1 which I have my husband and mum to look after him).

And I’m just so frustrated because I’m over people telling me what I should do and that it’ll be better for the baby.

If I’m not ready for something, I don’t need to do it. There’s no rush. And I’m sick of being made out all the time to being horrible because I don’t want to leave my son with them.

I feel like people forget he is only 4 months old, not 4 years old.
