My daughter who has turned 3 & half yr old ,has stopped sleeping ( taking naps ) in afternoon . Earlier since birth,she used to take 2 hrs nap in afternoon,but she doesn't sleep at all now.Besides dis,there are no other significant issues with her,rest everything is ok.She does sleep in night like before.I am just concerned about this sudden drop in her afternoon nap as this change is sudden .Pls give your valuable feedback on this
