Hello and welcome to BW forums
And congratulations on the arrival of your new LO
The advice is to breast feed on demand and yes he is probably having a growth spurt, the regular feeding will let him have what he needs and also cue your body to produce to his requirements.
He will probably go back to eating a little more spaced out after the growth spurt.
With EASY you don't have to feed at every nap wake up (if it has been a short time since the last E and LO is not showing hunger signs) and you don't have to make LO wait for a feed, just aim not to feed to sleep to avoid a feed to sleep habit. At this age though it is hard not to feed to sleep so when it happens don't beat yourself up about it. Try not to worry about bad habits or props at this point, but instead feed on demand and see if you can get into something of a rhythm with sleep.
If LO falls to sleep on the breast you can put him down and tell him you are doing so and you can still shush/pat in the cot to help him settle, this can pave the way to sleep training in a gentle way.
hope this helps
