Has anyone tried this? My baby is 10 months and will sometimes sleep through but often wake up around 5. I'll feed him, change nappy. He used to go to sleep after 15 minutes of babbling in his cot but will now just cry. Sometimes if I pat him for an hour (literally) he will sleep again. Routine is half hour sleep 9:30-10 and then nap 12-30-2:30 ish. If he sleeps less in day, doesn't impact night. Wondering if sleep training would work as it feels too late in the morning-probably less sleep pressure? Thanks !
