Hi everyone, I was hoping for some advice regarding my daughter who turned 2 a few weeks ago. We also have a 5-month old daughter. My 2yo used to be a great sleeper, went down at about 7pm and we didn't usually hear from her until after 7am the next day. When she woke she would just chill in her cot. Same thing for naps, she didn't do really long ones but usually 1-2 hours and she would just chill at the end.
A few weeks ago, we noticed that she occasionally needed us to come back in after leaving her at night, just for a quick cuddle. This has quickly escalated though and now she’s basically refusing to go to sleep at all, at bedtime and nap time. She is also waking in the night for long periods. The first time she woke at 3am and we had no clue what was wrong so we tried everything (cuddles, calpol, our bed - which we rarely do because we all hate it, her included). Eventually she fell back to sleep at 6am with me sitting by her cot and stroking her. She now refuses to go to bed without us sitting with her and patting her. Sometimes this takes 15 minutes (great) but sometimes it takes hours. We have tried letting her cry it out but she either poos herself, makes herself sick or throws herself out of her cot... She is also waking in the night regularly now and we have the same issues. I have noticed that she goes back to sleep faster when she is in her own bed and it's dark (which is a good thing) but it is taking hours and our 5mo is still waking 1/2/3 times a night so we are all exhausted 😴
Does anyone have ideas or tips? Should we try crying it out but for short periods? I can't leave her in poo/sick/on the floor and this normally happens within a few minutes of leaving her though. We have tried talking to her about this but she doesn't really give anything away. When we go in she normally says "get out of bed" or something similar but that's about it.
She doesn't seem to respond well to a night light as it just makes her more awake, but I haven't tried it for more than an hour here and there.
Has anyone experienced something similar? I wonder if it is separation anxiety and (partially) linked to her new sister?
Thanks so much in advance for any help that you can offer.
