Yep - crazy house is right.
My DD was always soooo mature. When she was 12 months old, we thought she was soooo old and started ttc - I was pg when she was 15 months old. I thought we'd be fine - and it wasn't too bad - but there were certainly challenges. The biggest issue for us was, no matter how OLD we thought Madeline was at 23-months, she was essentially still a baby. She looked so big the day she walked into the hospital to see me & Ryan - but she couldn't climb up on the bed without help.
She still needed me to do so many things for her (or with her) that I never really thought about. So don't be surprised at how baby-like your oldest seems after you have the new baby home!
Second, my son was/is VERY high-needs. He had reflux and colic - and was just generally not happy for nearly his first year of life. So I spent a lot of time just trying to meet his most basic needs - I was sooo tired! He didn't sleep AT ALL (really, I mean this - nothing more than a 10 min catnap here and there - I have never seen another baby like him!) and that made things hard. I also had a severe case of mastitis 1-2 weeks post-partum which left me miserable in bed - I couldn't do anything!
Third - my personal situation really affected how smoothly things went too - we moved TWICE during Ryan's first year - so our whole world was torn apart twice - that's not easy for anyone - especially not young kids.
Madeline was too young to really be interested in Ryan - she didn't want to help with him - and basically didn't even acknowledge him for months. It's kind of funny when I think back on it.
But - we got through it. And there have been some good things that came out of it. First, Madeline and Ryan do not remember a time they weren't together - and that makes them close. Maddie doesn't recall there being a time that she was the only child. It's also kind of nice having 2 kids so young - they like the same things! No complaints from Maddie when we'd play with baby toys - or watch Baby Einstein - she enjoyed the same things.
It did complicate doing things - like just going on walks - because I had to phycially help Maddie while toting Ryan around too. Slings saved our lives! LOL
I am glad they were so close - but I wasn't going to do it again! LOL
You;ll be fine - I think Ryan's high needs and Madeline's personality had a lot to do with our challenges too. Other kids would be different.
