Nap Regression

So Maddox has refused to take a nap the last two times I have put him down. And when I say refuse I mean sat/stood in his crib and screamed for 45+ minutes!!! I am really hoping this isn't a new reoccurring thing for him because mommy needs nap time!!! Hopefully, its just some weird thing these last couple of times that he will get over very quickly!!! HOPEFULLY!!!
