18wk DD sleeps in her next-to-me in our room, but with the side up and away from our bed. The other night she woke up half an hour after being fed and i just couldnt face it, i lay in bed for a minute while she cried - she was definitely awake, i could see her through the mesh of the cot side - and after about 30 seconds she was just grizzling, 2 minutes later she was asleep again.
Since then, if she's been fed in the last 3 hours (max she goes without in the day) i just leave her to sort herself out for a bit if she wakes and cries. 90% of the time she's back asleep within 5 minutes, and as soon as she gets actually upset and not just grizzling i go and get her and cuddle her back to sleep.
I didn't really think of it as sleep training cos it kinda happened by accident but then i read something about not doing any sleep training til 6 months and now I'm worried. Tbh, i feel like she's learning how to go back to sleep by herself, rather than crying herself back to sleep, but I'm stressing about going against the "rules". DH says "fuck the rules, take the sleep" but he's a renegade and i was a prefect, so that approach makes my teeth itch.
