Reply to 2 under 2?

Well I just started ... I have a 1 week old and a 23 month old (so she’s close to 2 already, a little older). But my oldest has really been having a hard time at night. She doesn’t fall asleep until 11 or 12 every night which is horrible on me and makes me want to cry! I’m hoping she will come out of it, and start sleeping by herself again. She loves the baby, and wants to be with her all the time which is great. I’m also struggling to get my oldest outside to have play time everyday, but I’m sure I’ll get into a schedule as my youngest gets older.
