How long does your 21 month old sleep? My boy is having trouble going to sleep at night. He still defo needs his nap cos he goes down so easy at lunchtime (around 12.30) and I have to wake him after 1.5hrs and he’s really grumpy... then I put him to bed about 7.45/8 but he really resists for hours. It hasn’t been long that it’s been like this so I’m hoping it’s just a phase but just needs some reassurance!!
