With any routine change (starting EASY, changing A time, etc) it does take some time for their bodies to adjust to the change. All the work you are going to be putting in now, will make a ton of difference down the road and you'll be so very happy you did it.
I think it's great that you are starting EASY.
It's a wonderful concept and is all about respecting your lo's needs.
When she wakes up at 5am, what is she doing?
Is it at 5am exactly every single night?
When they are on solids, they usually have solids 1 hour after having a milk feed.
But, you can do it 30 minutes after....there are no set rules. It's more about when your lo needs the feed.
How long is your cat nap?
If it goes until 5:30 you'll want to aim for a 7:30 asleep time.
That will help insure that your lo does not get OT.
Your routine looks good...just go into it knowing that those are ideal times and most likely will not happen at those exact times. You should base things on when your lo woke up last.
For example: Say she napped from 9:00-8:30am...your next nap will be at 10:30am instead of 11:00am since you want to have her asleep by the 2 hour mark instead of having her stay up 30 extra minutes thus possibly stirring up the OT monster, which is no fun to battle.
I hope that makes sense.
Do you have a good nap routine in place?
That will really help your lo know what to expect and get her body in the mindset that it's nap time.
Nice and quiet and dark, etc.
