I have just started to get my 4 1/2 month old on to EASY because her naps were getting shorter and shorter, down to ~25 min. It worked well yesterday but I keep questioning if she is hungry or not. A big part of the problem is that she is feeding every 1-2 hours. I have been trying to get her to feed for longer and lengthen the time between feeds which I'm sure will take some time, any advise on how to know if she is still tired vs hungry?
