E. A. S. Y. routine

Anyone follows the E. A. S. Y (eat activity sleep you) routine for their LOs? My LO is only 4 & a half weeks so I'm not looking to enforce any kind of strict routines whatsoever, but the E. A. S. Y seems sensible to start incorporating into LO's daily routine. I started to do activity time after he fed yesterday and he did go down for a nap easier in the early afternoon ; he usually refuses to nap around 9 am - 1 pm. Today I also did activity time and put him in the baby wrap afterwards, he fell asleep immediately. I still feed him on demand, tho. (exclusively breastfed) Curious to see how other mamas get on with this routine!
