How long do your toddlers nap for? I thought 2 hours was about right for my 16 month old so wake him after that but he cries and cries when woken. He has recently transitioned to one nap. He wakes early in the mornings and is taking a while to settle at night so I thought cutting it at two hours would be the right thing but he is so grizzly when woken (and also in the mornings where he is used to having a nap).
