My five month old had been on the four hour easy routine and it was working perfectly. He feed at 7, 11, 3 and 7 plus dream feed at 11.30. He has always been great for taking his naps which I make sure are never longer than 2 hours. Last week he started looking for a bottle at 6 and would still take his 7 bottle before bed plus he is waking at 3 for a feed. We did use the pick up put down method but he would wake an hour later and was rooting at the boob for a feed. Is this an indication that he is ready for solids???
