A.R.
Both of my kids were like this J. - I wound up bringing them to bed with me during the night so that we could all get some sleep. Then I gave up on the daytime napping almost entirely - thanking GOD each time they actually would take a nap alone. The frustration of expecting them to sleep was greater than the effort it took to keep an eye on them.
Some kids are just too busy to sleep during the day. I have two of them - both have turned out to be top-of-their-class smart and interesting people to talk to. I am, however, glad that they are no longer toddlers. Boy was I tired!
