Once again, I'm thinking about re-introducing sleep training for my 11 mos son. We did great around 5 mos but we took a fateful vaca right after he was trained and it threw him off and ever since then he's had really bad anxiety about being in his crib because he knows that we're leaving him. So I've just been patient and trying to help him not have such a fear of the crib, but lately I've been wondering how much our sleep training has been more difficult because we live in a small 1 BR in NYC. If he had his own room, I wonder if we would have been more successful. Any tips or advice for this EXTREMELY TIRED MOM and SON for those who have sleep trained in a small apt.
