R.D.
Did someone say nap?! Can I have one?!
Your son is doing what my son did... and it didn't get any better. He just doesn't need the sleep like my other kids did! My girls were ANGELS, they would sleep like 16 hours a day. My son... not at all. It does get a little easier once he's sleeping through the night, but man... I miss real, solid naps.
I feel for you!! Hope it gets better for you, because it hasn't for me!
