I kind of Gina Forded my first, mainly because I knew nothing about babies so it seemed like a nice way to have someone tell me what to do!
I didn’t stick to it rigidly but I did follow the food/nap/play ideas, had naps in a dark room, minimal eye contact (although plenty of cuddles) at night, plus the dream feed etc.
He thrived with a routine (still does at nearly 8 years old), slept through at 3 months, still is an excellent sleeper.
Second baby - he had to go with the flow, naps in the car/pram etc. I was also knackered so let him feed to sleep, co sleep, he had a mild routine but nothing like the first.
He didn’t sleep through for 18 months and still at 5 isn’t such a good sleeper, although miles better. He needed me to stay with him and couldn’t self settle for bloody ages as he got so used to sleeping in a sling or on me.
BUT, they’re both fine, great, lovely boys. The small one still comes in for night snuggles and I LOVE it as he’s a little snuggly sweetie.
