My (very nearly) five year old does not sleep through. He wakes at least once per night and bedtime involves frequent meltdowns, tantrums and general faffing and prevaricating by him. He will sleep often better in his siblings room, or in our room - on a mattress on the floor. Often he’s not asleep until 8, which I think is quite late, considering how active he is. He’s had cranial osteopathy once, with limited short term success. He does a double wee before bed, not hungry, thirsty either. Any advice would be great - thank you.
