DD is 11 weeks and goes down between 1700 and 1800, sleeps till 2200, has a feed then 6 nights out of 7 sleeps through till 0700. She's done this since she was 8 weeks with the very occasional feed at 0300.
A friend told me that her secret of getting her DCs to sleep through at night was plenty of sleep during the day, putting them down to sleep before the 3rd yawn and NOT going in the instant you hear a peep after they've gone down. Like everyone, I've learnt the difference between a "I want some attention but don't need it" grizzle and a "I need you" cry and react accordingly. Oh and I feed to wake except at 2200 and the feed between 1700 and 1800.
I feed on demand and DD's "routine" is one that she has put herself into so if it deviates then that's okay, they're her rules. She drinks about 200mls per feed and weighs about 15lbs at the moment. She's growing out of her 3-6 months jumpsuits already so not a little girl, not fat I hasten to add just very long!
Rough routine is as follows:
Wake at 0700, feed, playtime mostly cuddles as she's delicious, pottering about
Walk the dogs 0800
Snooze at 0930
Awake at 1100, feed
Playtime, pottering about
Snooze at 1230
Awake at 1400, feed, playtime
Walk the dogs 1500
1700 Bathtime, story, feed and bed
2200 feed
This is my first child and I purposely didn't read any parenting books so right or wrong.......this is what works for us.
