Congrats! And no she won't be able to sit up yet. We went to DL last year when DD was 4 months old. It's a little tricky to bathe such little ones. I'm thinking the easiest thing would be to have someone else help you. Have one person hold her in/over the tub and you bathe her. As far as using the sink, we stayed at ASMo, and I don't think the sinks were very big/deep, but than again she'll be pretty small still, so that might work. There's also places that you can order stuff for babies, and they deliver.-No idea on how much it costs. I don't think we'd do it, but just something to think about. Also, I don't think I'd try the showering with the baby. I tried that once with my then 1 year old DS, and seriously almost dropped him. It never dawned on me that he'd be slippery, and very very slippery, and he was 1- I'd be scared to death to try that with a 2-3 month old. I also wouldn't even try to bathe her every day though. I think a few times in that week would be fine. Have a wonderful trip!!
