Well, basically, you aim for a 12 hour day. If it will help, my routine with DD at that age was
7- WU+ top & tail+ nurse
8-10-- nap 1
10- nurse
11.30-1- nap 2
1- nurse
2.30- 4-- nap 3 but this was only ever 40 minutes. So ended by 3.15 mostly.
4-nurse
between 4.30 & 5.30 - CN of 30/45 mins
Nurse on Wu from CN
And then I would split the last feed around bath
5.45 Nurse
6- bath & massage
6.20ish - nurse
7- bed
Between 10 & 11 - dream feed
As you can see, our routine was messy due to short naps but it helps to know what comes next, so you're not left wondering and confused. And since she was in bed by 7 , I got some time to myself to relax, cook dinner, etc. Do you think something along the same lines might work for you? I also want to add that I nursed whenever she asked, irrespective of how long it had been since her last feed. You want him to get most of the calories during the day, so she is not waking up hungry at night (which he still might though) and nursing frequently also helps to build up your supply.
