I was completely floored after dd. I genuinely didn't know what had hit me.
Not only was it a shock going from no baby to a baby, she would scream constantly (colic - not an exaggeration) I was bf and exhausted, I had PND and couldn't put her down for a second, because if for some blissful reason she was quiet, that would set her off again. Bf was hard because she'd fuss so much I thought she would starve.
I honestly felt that I couldn't do anything. I was in tearful awe of the new mums who were brushing their hair, getting washed, not sucking at everything (that's how it feels, like your baby hates you for being so useless)
It got easier as she grew. And then I accidentally got pregnant with ds. I was horrified and had no idea how I was going to cope with two, one had nearly destroyed me.
Turns out that ds was a completely different kind of baby. He happily lay anywhere you put him, if he could see you he was fine. Occasionally he would whinge a little (not crying) while I finished up my shower but not that ear piercing scream of the colic baby. He slept for more than a half an hour at a time! He bf like a pro and it was so much easier.
Obviously he was my second so I sort of knew the drill, but it wasn't just that. It was like dd was 'hard survival mode' baby and ds was extreme easy mode.
You shouldn't judge anyone having different motherhood problems to you, or not seeming to do as well.
