Just wondering how much physical activity your toddlers do daily? DS has just turned 18 months. Sleep has been a nightmare due to reflux, cmpa and egg allergy, but has been slowly improving over last few months. He now sleeps through at least once or twice a week. The latest issue has been not actually falling asleep until 9pm or later, even though he's clearly been tired from tea time. So yesterday, after his nap (12-2), I decided to make an effort to tire him out. We went to a big park where he walked around a large lake and had about 15 minutes playing on the park. Last night he was asleep by 7.30! Unfortunately not all night, but one wake up for calpol and a cuddle and then he went back off until 6.45! I realise it may have been a coincidence, but also wondering if he needs more activity than he's been getting...
