    growth spurt, teeth... Belly... His mind is now thinking of fun things..
    I'd make sure his naps are before 3pm or earlier if you can. Shortened to no more than hour and a half and one a day.
    Then when he wakes up be SURE to stay consistent in putting him back down and leaving him there.
    Kids go through SO many sleep changes. Just when u get it down they do this.. It's exhausting.
    But stay consistent so he knows there's nothing to wake up for.
