I'm very overwhelmed!

so we have an 8 year old and it took a long time to finally have another baby, I had another baby 10 months ago, so we have a 10 month old and an 8 year old. we struggled with unexplained infertility for so long I never thought we'd be pregnant so soon again! we both thought it'd be cool to have the next one less than 2 years apart, but I really really didn't think it was possible!!

I was late 10 days but I'm irregular with nursing right now, I went and bought 2 tests and the first one had a line in the test area before it even fully filled up the window!! it's a definite positive. I'm very happy, however I'm scared this time....my 10 month old refuses to sleep very much, and never took a bottle. she's a very tough baby. we are going to start working on getting her off the Boob by 12 months and sleeping in her crib...we will be using a bottle right away with the new baby and trying to get the baby in a bassinet right away this time around. the babies will only be about a year and a half apart! any advice would be great thanks ladies
