DS is 28 months. I am due with DS#2 in January when he will be 33 months. We need to transition him to a new room/bed (he's already in a toddler bed but he's going to move to a queen with rails). And we need to potty train. I don't want to do either too close to my due date because that in itself will be a big transition right? I don't want to overwhelm him. What transitions did you need to make with your first before baby came and what timing worked or didn't work?
