Thank you Shiv and Ali!
That's a good idea about the diaper change. We were all ready to do Pu/PD last night, but I fed him at 7, 9, and 11 (per the example) and he STTN- ha! Figures. I did use ebm for one of those feedings which might have been why. When I try to tank up just using my breast, I don't think there's enough there for what he's willing to eat.
So tonight, I fed him as normal, then ebm an hr later before bed. Will do the DF as normal by nursing and just keep experimenting!! Thank you again - tbh, I don't think I could've gone through with pu/pd if I knew for certain he was hungry
And I definitely won't be doing it if he does wake during the night for a feed, either. It's definitely not habitual and I see that now.
