My 3 month old will only sleep while been held, she wakes as soon as I put her down, I've tried waiting until she is fully asleep, swaddles, dummies, different beds, things that smell like me, white noise etc, all I'm reading online is to treasure it and make the most of them sleeping on you, sleep deprivation aside, I also have a 2 year old who needs to be cared for during the day, it seems that baby will go to sleep then 2 year old will get into somehow she shouldn't, i get the baby to sleep again then she does a poo, get baby to sleep again then it's lunch time, you get my drift. She's overtired as she's not getting solid sleep until 2 year olds nap time or night time. I'm concerned about her development due to lack of sleep. I get she's only 3 months but for her own good I need to be able to put her down so she can have some decent sleeps through the day. How did others with 2 close together manage this? Wraps and slings are no good as she rarely sleeps in them and will still wake allot when she does.
