Hey Michelle
Vaden learned to self soothe really early on in life (thank heavens for my angel baby), but when she started pulling up, the sleep stuff got really irritating, and I used pd, and it worked like a charm! I don't really do it anymore even if she isn't sleeping great for one odd nap - I do more AP, but if it starts to become a problem, then we go back to pd. Good luck, and I hope you find what you're needing to get him sleeping well!!!
