But, if you are not that lucky and your child simply does not nap or wakes early from a nap, the lack of sleep will make them grumpy and intolerable and by dinner time a crazed animal, by bath time a scary crying monster and at bedtime they just crash out in a few minutes only to wake lots during the night or at 5 am in the morning ready for breakfast and acrobatics around the living room..!. I bet this sounds familiar to you?
