Hi, there is a 23 months gap between my girls

I LOVE it. In the beginning when baby was a newborn, my older daughter was so loving of the new baby, don't think she understood to be jealous! At 2 she didn't really have tantrums, ( not big ones anyways) I could trick her into being busy while I had to nurse so often ( sticker books, new book, playdoh, etc)
When the baby is bigger and can walk and play, I think they will play a lot together ( ESP since both being girls I guess) the older one wants to " teach" her little sister everything. In the fall when my daughter is 3 she will go to preschool a couple mornings a week, which gives me a few hours those days of 1 on 1 time with my little one.
I think if I had my baby now that my older one is a bit over 2 1/2, it would be rougher. Now she is starting to have bigger tantrums and is more stubborn, but the baby is no trouble now.... So I can deal with the toddlers crazy mood swings easier while the baby sits and plays with toys...
Anyhow, I love the gap, any gap has good days and bad days. Just roll wi the punches and do the best you can. There are definitely hectic moments, but don't be hard on yourself. If somebody is crying a few minutes while you have fix the lunches, it's not a big deal in the grand scheme of things. They will get attended to once your hands are free, and life will go on. ( just hopefully YOU'RE not the one crying hahaha)
Best wishes!
