I had a baby just over a week ago, at first it was a little overwhelming but now I find myself gettin upset a lot, my partner was over the moon at first about the baby but I don't know if the novelty has worn off? He was more than helpful at first, but now he will gladly let me do the night feeds and day feeds/changing baby, he even went to sleep downstairs because it was too "hot", more like I was keeping him awake feeding, I find myself crying alot now and feeling all alone, is this normal?
