The thing with EASY is that it is meant to be a routine, not a set schedule, so it is more about the pattern of the day than exact 3 hour timings. 2 hours is an average A time for that age I think but depending on the baby could be more or less. Around his age I actually did EAEAS because A times meant that the next E fell during a nap so I did a top up feed before the nap (not feeding to sleep, just a small feed 15/20 min before nap time). Does anything work to extend those naps?
