absolutely. More than a 2 hour nap can interfere with them sleeping as soundly at night. And it helps make sure you're getting more calories in during the day where you want them, instead of at night. When dd was your lo's age is about when we started EASY, and I was pretty strict for the first few weeks and watched the clock pretty closely. It was the best way for me to get everything in working order, and then we were able to be more flexible with times and feedings and naps, but in the beginning if it was time to eat, I woke her up and fed her, and if she was tired shortly afterwards - and couldn't handle the 1hr A time, I'd put her down a little earlier, and let her go a little past two hours if she still needed it for the next nap, but still got her up at the three hour mark to feed. After two weeks of sticking to a really strict routine dd was sleeping through the night from 8pm-7:30am with a dream feed at 10 which was great! Good luck I hope that helps!!
