Hi and welcome to BW

I'd suggest just recording her EAS times for 3 days to see what sort of pattern emerges. I think Tracy suggested this for moving onto EASY so that you are taking into account baby's signals and cues as well as introducing a regular predictable routine.
Even if it feels like there is really no routine oftentimes when you write it down a pattern emerges, or we can help review it with you. Just write down the times things actually happen (not what you hope for) like this
WU 7.00
E 7.15
A
S 8.30 - 9.15
A
E 10.30... or whatever the actual times are.
Even though we were on EASY from 4 wks whenever something went off track I always started to record our times again, it would help me see what was happening, and helps the BW community to offer individual support.
