You can try transferring him to bed when he’s sleeping.. Or you could also consider just taking the yaolan away completely and doing sleep training using the bed. Also train self soothing by not attending to him immediately when he calls. Give him 3 minutes, then gradually 5, then 10, and so on. Let him learn how to fall back asleep on his own.
I gave my baby sleep with me at night and nap in yao lan. You cna slowly during night once fall asleep love to your bed.
i'll only let LO sleep in yaolan during afternoon nap. other times, on the bed
I only let him nap on yao lan ..at night I will pat him to sleep on his cot.
Can start with a sleep routine and stick to it.
