Gifts for siblings?


My son will be 4 when the new baby is born. I was planning on getting him a gift, one from the baby, one from me and my partner. Only thing is, im stumped what to get him. I want to get something he would like but could keep forever. I thought about getting him a toy but in a year he'd be bored with it, I thought about jewellery but what 4 year old wants that.

Any ideas?

FYI, I don't know the gender of the new baby until it's born
