any suggestions how to tackle my DS's(18 wks) inability to nap in his cot? In fact he only wants to nap while being pushed around in the pram. This wasn't a problem in spring & summer but I am a bit reluctant to spend 3 or more hours each day in the rain trying to get him to sleep! He will now also sleep in his pram indoors but has to be pushed to sleep first.Our house isn't huge so this isn't very convenient and I also worry about him not learning how to nap cot when he's 9 months and has to go to nursery! Any advice please?
