Hi all! My previously sleep trained 14 month old (STTN since 9 months and great napper) has been scream crying as soon as I put him in his crib for naps which was not the case before. Ferber not working at all (he stands up for the whole hour and wont lay down). We are on 2 naps (3/3/4), however I decided to give a 1 nap day a try yesterday and he went down at 11am without a single tear and slept for 3hrs. Today he woke up at 5am (DWT 6:30) crying. Tried to put him down for his first nap at 11am and scream cried again and Ferber failed. What am I doing wrong? Is he not ready for 1 nap?
