Dream feed help

So I follow the baby whisperer book which is similar to baby wise. My baby is 10 months old and we've been on this schedule since about 4 months. He wakes around 7 and I get him up at 7:30. He stays awake for 3 hours at a time. So roughly our schedule is 7:30 nurse 8:30 yogurt and fruits 10:30 nap 12:30 lunch and nurse. Roughly 3 nap 530 dinner. 7:30 nurse and bed. Then a dream feed around 10. I want to drop the dream feed but don't see how I can fit 4 nursing sessions in. How long does your baby go through the night without eating? I'm concerned if I drop it and don't put it somewhere else that he will start waking early. Any help is appreciated.
