I wonder if u guys will have too much going on to be starting EASY? Solids, just back from holls, moving to his own room and keep in mind a major growth spurt around the 6mo mark.
As far as I know most parenting books, including BW recommend to start solids, only when ur los r feeling well, sleeping well and have a fairly well established routine. With so many changes all at once u r nearly guaranteed OT, nap problems, NWs etc, I just wouldn’t think this would be an ideal time to start solids.
U mentioned a lot of major issues u want to tackle and change. I would personally pick one thing at a time and work on it. Is there any chance u could start easy gradually? If u post what ur typical day looks like we can see if anything can be tweaked to get it to resemble EASY. This will establish some basis for u to work with and help manage all those changes.
U can try to stop BF to sleep now and use pu/pd or shh/ap instead, u don’t necessarily need to be on EASY to teach him to fall asleep independently. U can keep feeding before bedtime in the evening, just make sure he is fully awake during the feed and when u put him into his cot he is wide awake and then do shh/pat or pu/pd.
If he had a feed at 4am and then settled back to sleep treat 4am as a NW, feed if he is hungry, then wake him up at 7 am and start the day, give the first feed, then A, than am nap.
Do post what ur day looks like at the mom, maybe there is a way to start on easy now, jus baby steps to put u on the right track and so u won’t have as much to work on later.
Hope this helps
