Hi RENI, unfortunately we aren't going better

I decided to change our daily routine, I add a cat nap in the late afternoon because I realized that he was always too tired.
So now he has this routine
Wake up 7
A 7-9.30
S 9.30-11.00
A 11-1.30
S 1.30-3.30 (he sleeps a lot here, sometimes I have to wake up him)
A 3.30-6
S 6-6.40
A 6.40-8.30
S 8.30
In the night he eats only one time, at about 3, 3.30, but he has several night wakings, about one every hour and half.
He just need my shhh and pat for 30 sec.
Yesterday I tried to make him sleep only 20 min at the last catnap and then I put him in bed earlier (after only 2hrs of Activity). The night was super! He slept from 8 to 2, when he ate, then he woke up at 2.40 and then at 6 (he ate) and then at EIGHT O'CLOCK!!!!!!
But sometimes he sleeps well only for one or two night, so I don't know... maybe the next will be a dreadful night... Who can know...?!
