Quoting Rista Kat:" When your child stopped taking naps - what did you do so they weren't so cranky when 4 o'clock rolls ... [snip!] ... a mess right behind me. I know that sounds selfish, but if there's no more nap time, when did you find time for yourself?"
I'm dealing with this right now. The last two weeks LO has only napped twice I think. I've been putting him in his room for quiet time for about an hour and doing what I need to do. Also, I'm putting him to bed about an hour early!!! That's the best part for me, lol!! I work full time though so I get out of the house often.
