My dd is supposed to start gymnastics today at 4. She is 3 1/2 and it would be her first day. She always takes a nap everyday, and if she doesn't she is EXTREMELY crabby and whiney. She will not take her nap today and I know my dd well enough to know that if she does not sleep this afternoon going to gymnastics will be a nightmare. The class is 45 minutes away and I have to go to the store while I am there after the class. I really dont want to take gymnastics away from her but she will just get me VERY ANGRY because she will be whiney and crabby. What would you do?
