My first baby was a shite sleeper and I very nearly spent several hundred euro on a sleep consultant after listening to Caroline foran prattle on about one. I saw sense, and some time around my baby's first birthday she just started to sleep through even though I wasn't doing anything different. She never slept in a car seat, or buggy and still won't so we always had to work around her naps in the house.
Second baby is a great sleeper, sleeps in his buggy, car seat, in the sitting room with a toddler screaming. Doesn't bother him. Even at night he's sleeping long periods, not completely just yet but he's only a few months old.and still breastfeeding. I did absolutely nothing different than the first time. Don't let these instagrammers fool you, it's nothing they did, or paid for. It's luck or I'm pretty sure in the case of Lisa a big lie to make herself sound better, you are doing a great job just as you are and one day it will click and they will sleep through for you.
