My daughter's nap time is usually 2:30-3:00pm. I'll try to keep this nap time thing going no matter what. But of course if things happened and the time past, I'll still let my bb take a nap as soon as she gets home. If your BB haven't have a nap, he/she will be very very cranky. It will cause you alot of trouble. One time I didn't let my BB take her nap and she was soooooooooo cranky and naughty and refuse to eat dinner, actually refuse and ignore everything I said. It was the worst day ever !!
