Hello, my son is 2.3 yr old sleeps only once in a day in a gap of 12 to 14 hours...my mother says that it's very necessary for toddlers at this age to sleep in afternoon as well..so I started waking him in the morning early and make him sleep in the afternoon and again he sleeps late in the night..but every time when I wake him up he is mostly into deep sleep in morning and in afternoon too and he becomes crancky and doesn't wake up in Happy mood .should I stop waking him up forcefully..
