T.; yes the ability to stand does make nap time a bit more challenging, i spent a lot of time with my first child thinking he was supposed to get a nap, i worked all day trying to get him to lay down, just like you , books, rocking etc, nothing, finally he would tire out later in the day which kept him up later at night, then i had my second child, that was nearly impossible to get him to take a nap, you never knew when he was tired, or when he would wake up if he did, then i had my third child and i wish i had learned this with my first, some kids dont need naps, some outgrow them very fast, to spend time making him sleeping when he is not, is wearing you down, ive learned that a kid will sleep when he is tired, as we do, we know our bodies are shutting down, and we fall asleep, he might enjoy seeing the world from a different perspective, and he might have the energy to stay awake, now that he is getting exercise, i say , let him nap when he is good and tired, if he needs it, if not its ok too, my 3rd son thrived more so, cause i understood nap time better, any way , have a good day , and know your child, some will need it others wont, its ok if they dont need it for a while, and some will get it later too, some never get it like my first, ahahha D. s
