Just after a bit of advice - 20 month old DD who suddenly isn’t going to sleep until 8.30/9pm and waking before 6 after previously sleeping 7-6. Just wondering if it’s a phase that anyone else has been through or if it’s time to reduce her nap? Yesterday she had an hour and forty mins so not crazy long but I have heard of some kids not napping at all at 20 months! Scared to cut the nap incase she’s an absolute mess! Thanks
