My seven month old suddenly started sleeping and considerably less during his lunch nap. This was my only free time! Before he used to do one hour and a half, now it’s better now sometimes 45 minutes and then he’s just wide-awake. Is there some change happening? It’s at the naps haven’t changed so far; half hour in the morning at 9 AM in half hour later at four. Bedtime is 7 PM. Anyone experienced anything like that?
