My babies all did Sleep-Feed-Play-Feed-Sleep. I found they slept really well if I did that routine but they would often sleep so well and for so long they woke up hungry. I just made sure that I offered the same side for the second feed so that they were getting the hind milk and not just the sugary fore milk because that can give them bad habits for snacking. I have had problems with supply so that was really helpful to my milk.

Once my babies are on solids, as DD2 is now, I tend to give her some solids when she first wakes up, let her play, and breastfeed her before her nap. It works for us. I just follow what my baby seems to want and we have happened to fall into that routine. Even with the S-F-P-F-S, it was all baby led. All three just happened to enjoy doing it the same way.

FWIW, I stopped stressing about things like SFPS because I found it all confusing and some of the information can be very conflicting. I did try to do it at first because I was scared that letting them fall asleep while feeding was going to create bad sleeping habits or because I thought that I was doing it wrong. I have now got 3 kids and I just follow what my babies want to do. It hasn't affected the sleeping behaviours of my older kids to let them do whatever they want to do as babies, it just meant life was more pleasant for me because I could meet my babies' needs when they had them, rather than the stress of making them follow a routine they don't want to follow.

I guess what I am saying is that FPS is not wrong if that is what your baby wants, but I think more important than anything else is just following your baby's lead. Do what you are comfortable with and if you want to feed your baby to sleep, you are not going to harm your baby in any way or cause problems for yourself down the track. It is okay to follow your baby's lead if that's what you want to do
