My kids are 2 years and 2 weeks apart. I planned it that way. I also wanted them to grow up together. And I wanted to get my baby days done and over with. lol The end of my pregnancy was tough. Just going to the store with a soon to be two year old, was a challenge.
To be honest, the hardest part was being in the hospital. Nobody except my husband and myself every cared for my son. So it was difficult to shuffle him around while my husband was with me in the hospital. And I had a c-section so I was in for 3 full days. When mom came home and the rules went back into place, and then to have a new baby there on top of it, he went a little nutty.
With the birth of my first child the hospital room was party central. I always had visitors and didnt get much rest. With #2 I told everyone (except my husband and son) to stay away from the hospital. :) I knew that I needed my rest and these 3 days were the only days I would have to bond with my new baby ALONE.
With #1, he roomed in. With #2, I utilized the nursery at night. I wanted to get as much rest as possible. By the time I went home, I was refreshed and recharged.
My son ignored the baby for probably the first 3 months. He didnt want to hold her, and it was impossible to get a picture of the two of them together. He wanted nothing to do with her. That made it easier because when I had the baby he was perfectly happy to be anywhere but near us. :) He never tried to hurt her, smother her, bite her. Nothing like that. NOW, she is 9 1/2 months old, and he is rough with her. Things change.
I did have one melt down. My son was hungry and wanting lunch. I was boiling macaroni to make Mac and Cheese. Ally was in her carseat on the floor screaming her head off. Evidentially the four hours I spent on the couch nursing her werent enough. Joey was screaming because he was hungry. And I lost it. I dont think I had postpartum depression, but I think I had postpartum stress. Adding another one to the family is a big change.
And the best advice I can give you is to keep laughing. And enjoy every minute. AND stock up on distracting toys. Anything you can pull out of a cupboard to occupy your older one when you are about to pull your hair out will work.
Congratulations on your new addition! And Best Wishes!
