Baby shopping feels like something I need to do right now

I was in target tonight and it's hit me that I have so much to get for this baby and my two year old. My two year old has grown out of all her clothes and pretty soon her shoes. I have to get another stroller, clothes, bottles, breast pump, blankets, playpen. Plus I'm in need of maternity clothes. It's so overwhelming and I didn't realize how much needs to be done by May. I need to make a list...lol.
