14 month old DD has always been a dream when it comes to sleeping.
Up until a month ago, we had a solid routine of dinner between 5-6, bath 6:30, cuddles, bottle and bed between 7-7:30 and up between 6:30-7:30.
She dropped to one nap on her own just before her first birthday, this is usually 10-11:30/12.
She will sometimes nap for the odd 10-20 minutes if we have to go out in the car.
She is walking, says a lot of words, we play together, we walk the dog every day and she runs around, we meet friends at soft play etc so she's burning energy every day.
She eats 3 solid meals a day including healthy snacks and drinks plenty of water.
For the past month, she is up at midnight until 2/3am, screaming, won't settle, I've given her water, I've given nurofen in case it's her teeth (she has 8 but I think I can see a 9th coming through), I've changed her nappy in case she's uncomfortable, she's not cold and not too hot. She's always loved her cot. She has a black out blind, we keep her room a "happy" place as in if she does something like tip the dogs water bowl over for the 4th time we never tell her no and put her in her room, we tell her no and place her in her play pen so her bedroom is never used as "punishment" not that we punish her as such, just a firm no and move her away and place her in playpen.
Nothing in her routine has changed but for some reason we have 2-3 hours of inconsolable screaming and wanting to play in between cries.
I've tried cuddling her, I've tried laying her back down and saying "it's bedtime" and leaving the room (which causes her to cry so much she starts hyperventilating so I go back in). If I put her in our bed she just starts trying to play with me or DH, then she starts getting "grabby" because she's tired, pinching, trying to bite, pulling hair etc. so co sleeping doesn't work.
Basically, I would really like my good little sleeper back, my DH and I are shattered from broken sleep.
She's CMPA and on prescription formula but as she's over 1, this is now her last tub so I've been switching an extra oz each night for oat milk which she's always had on weetabix etc. could this be why? Could she have stomach ache? Her poos have been normal.
Any suggestions? Is now the time to proper sleep train? Gently, I'm not going to leave her to cry herself to sleep but we've made a rod for our own back by cuddling her to sleep every night which wasn't a problem until she started getting up at silly hours.
I need help!
