I don’t know why people automatically assume, gently encouraging a baby to sleep for a longer stretch at night means leaving them to cry in the night and not be comforted?!
I did gentle sleep training from about 6 weeks and they were never once left to cry!
All I did was at night, kept it as dark as possible, stayed in their room on the chair to hold them (not took them downstairs and put the tv on and stimulated them etc) minimal speaking and interaction.
I woke them up at the same time every day, that seemed to be the key. Soon as it was 7am I made it bright, noisy and carried on as normal (even when they were asleep.) I changed them out of pyjamas, washed them and put them in clothes for the day.
I used to put them to bed at 7pm and then do a dream feed at 10pm.
My daughter by 7 weeks had dropped the 2am feed and was sleeping through until 7am, she was a natural sleeper though and always loved her naps etc.
My son still needed a night feed until 9 weeks and then when he dropped a 2am feed he used to frequently wake up at 5.30am until about 3 months when he went until 7am.
They dropped the dream feed at about 9-10 months when they were on 3 meals a day plus milk feeds.
I’m never up in the night with them unless they’re poorly.
So please don’t assume that just because you don’t co-sleep etc that you’ve left a baby in a dark room to scream and cry and not be comforted!!!
