K.H.
I just went though the same problem with my daughter, she stopped taking her early morning naps then she was too overtired to take her afternoon naps, and super cranky at night she even stopped sleeping through the night. I adjusted her nap times and that has helped instead of a 30 min nap at 10 she has a 2 hour nap at around 1 (which was a hard loss for me because I always napped or showered during her first nap depending on what I needed to do that day) And now she takes her second nap around 6 for 30 min. I take her in her room and turn out the lights and give her a bottle and rock her, If she is really sleepy she will fall asleep in 5 min and if not we get up and play for about 30 min before we try again, I don't force the naps because when I did she would only sleep for 15 to 20 min then she would wake up just as cranky, you can also try reading that's how I get my little one to sleep at night I read her the same book (we switch it up every couple of nights) and I have never had to read a story more than twice to get her to sleep (It may sound stupid but I don't really let her touch the books we read at night so she knows that it is quiet time but when were in her room she can play with them) Hope this helps
