I understand how you feel about wanting baby to have his own room. But your mind in in fairytale mode right now. Motherhood is not a fairytale. You can try to fake it. But you will end up wasting time and money doing it.
Add up the cost of all of the stuff you want to make that picture-perfect nursery. Crib, mattress, bedding, wall decals, matching lamp, changing table, curtains, night light etc.
Now, imagine what that money could buy you in carseats or strollers.
You need either a bathtub, or bath support of some sort. We are getting a bath cushion thing that can go in the sink or the tub.
Swaddling blankets. Target has the Aden & Anis ones for cheaper. They are slightly different.
You will need either a high chair, or tableside booster with seatbelt.
You will need a place to put baby so you can go to the bathroom, shower etc.
Space is an issue in our place, so I've picked out a graco swing that converts to a bouncy seat. the seat lifts off of the swing easily and I can move it around the house. It is a little more expensive, but there are deals online. I haven't bought it yet, but I hope I like it. I didn't want two baby seat things to have to trip over. Plus, some babies like the swing, some like the bouncy, and some like both. I figured if I got a 2 in 1, if the baby only liked one of them, I wouldn't feel like I wasted my money.
