Good for you sweety! Honestly

You are preparing for your baby and that's great! I think you should buy what you want when you want.
I never understood people that waited for other people to buy things for their baby. If you feel the need to start preparing now, then do so! People will buy you whatever else you need

You wouldn't want to fully depend on other anyways, even if you have a good idea that they will be buying you lots.
