If you need any more suggestions, let me know.
How old? What’s your daily schedule? Are they awake and ready to play typically during split nights, or super upset? Split nights are typically either under or overtired but it can sometimes be a little tricky to figure out why. If you’re on one nap I’m assuming you have a toddler. Remember average sleep totals for 1-2 year olds are 11-14 hours including naps so I would first make sure you’re not aiming for too much sleep. Also make sure that when you make any changes you’re doing so for a long enough time for them to adjust and see if it’s working. May be a week or more.
How old is your baby? Mine did the same while she was around 6/7 weeks and it went on for a while
He has just turned 16 months and our routine was 1-2 naps during the day depending when he woke up after a split night - for example he could waken up at half 8 after a bad night and then doesn’t need two naps. We have a nap at 12 and then dinner 5, 6pm bath time and bottle after that and depending on how well he slept during the day he would be in bed at 6.30/7. The fact he is sleeping all night when he goes down in my bed for the night and not in his cot makes me think it’s not him being overtired/undertired as he can do it.
I am the exact same as you right now! My little girl is 14 months, and the last week she’s waking about 1am and that’s her wide awake usually crying wanting to get up, usually going back to sleep around 3am, she’s having 1 nap that’s usually an hour through the day so I’m unsure if there is some sort of big hgrowth spurt or slee regression happening, agajn the same as you that she’ll sleep in our bed no problem just won’t go back into her cot!
I don’t want to sound negative but this wee rascal has been doing this for a couple of months now. He can take a while to settle in my bed as well but it’s more he’s wide awake but he isn’t upset like he is in the cot. Sometimes I wonder if it’s the to and fro of going to his dads (we aren’t together), is that having an impact on him which makes me even more unlikely to fight the battle as when he’s away I miss him so likely I am not helping him by bringing him in the bed - enabling his bad habits!
Yeah it can be tough to get them into a routine if their bedtime is different from day to day. You're doing your best I'm sure
