When your child is sleepy, does he/she get even rowdier and more handful? God, my toddler becomes naughtier and kicks her sister with a matching maniacal laugh!

yes it is natural for babies and even toddlers and older kids to get cranky and aggressive when they are sleepy. just imagine, when we come back home from a long day at work, or if we are tired and super sleepy, all we want to do is lie down and rest. but young children don't understand that the reason they are feeling uncomfortable is because they are sleepy and need to rest. also, they want to always play and do as much play time as they can, which aggravates them further. i always make sure that i make my kids eat and get in bed before the sleep or tiredness takes over and it gets difficult to handle them :)
