Toddler waking up fussy

Nicole

Hi all!

My son is 21 months old, we noticed over the past 2 months, he often wakes up fussy and cries and nothing consoles him for like 10 minutes. I believe this started when he started napping in his crib, before he would nap in his stroller after pushing him. Any idea why is he doing this? We offer milk or snacks when he wakes up and he just throws them. He hardly wants us to even hold him at this point. :(
