It really does depend on the baby.
If you think your baby is better with F-P-F-S than go for it - it has to be aboout what works for you, not what other people tell you. We only know what has worked for us
DS1 liked this and his day sleeping settled down once we move to feeed-play-feed-sleep

DS2 is a lot more flexible sleep wise FPS or PFS both work wel for him.
