Hello,
I'm using shh-pat since he is 2,5 mo. Today we were out for breakfast and he slept at the second end of second hours A time (first A time of the day). And then he played for 40 minutes in the second nap and 1 hour at bedtime.
He woke at 3:30 pm from second nap and I put him to the bed at 7:00 so that he wouldn't be overtired. However he played for 1 hour in his bed and then slept.
If he will have 3 hours A time then I don't think that he will sleep as 3 hours A time and 1,5 hour sleep time makes 4,5 hours in total which will be more than 4 hours which he is used to be fed. In case I follow your suggestion how would I adjust E time?
