I just put our little guy on a 4 hour EASY last week - cold turkey and very successful! He is on it like clockwork. Well, he was.
In the last few days he has suddenly been waking halfway through one of his naps (morning or afternoon. Sleeps almost exactly 45 minutes for catnap).
We can 'shush' him and it works about half the time to get him back to sleep. The other half, he is freaking out.
We had tried PU/PD with about 50% success when having some issues last month and chose to stop due to it not always working (sometimes it made it worse) and LO has a touch of silent reflux we don't want to aggravate.
W2S seems to be unlucky too - each time we go in, he is already laying in his crib with eyes open.
Is this a regression?
He just barely makes it 2 hours for A time and does great with eating every 4 hours.
