Our baby slept through the night for about a year (obviously except when I'll or upset etc) . went through a what looks like a sleep regression with generally one night waking quite regularly in the week (around 4 times a week ). tried everything to get back to sleep quickly (reassuring, cuddles, song, music, silence, night light, persuading). but fail most times: she just wants to cuddle mum foreever. this has lasted 4 months so I guess last step is putting our foot down/sleep train because we are no longer able to function properly during the day due to sleep deprivation. Any one gone through this or tips ? thanks
