DS is nearly 13 months and is transitioning to one nap here and there (still has two at nursery).
On his one nap days, unless we are at home contact napping, he will only stay asleep for about 40 mins.
Everything I read online says the one nap should be at least 1.5 hours if not 2 hours.
I wondered if anyone else has the same issue, how bad is it for him to have just one short nap all day?
