Twins on same schedule/food before bottle

Steph

How long were you able to keep your twins on the same schedule? Mine are 10.5 months and I have been pretty lucky so far. My son wakes up early a lot and I let him sleep on me till she gets up or its closer to feeding time. 

I want to start to give food before bottle, even before their first bottle of the day but I'm know i will have two crying babies then. I dont know how to make the transition? They dont eat enough food. Still working on getting them to eat table food. They get bottles 4 times a day starting at 630. They eat every 4 hours. They get food 8am, 12pm and 5. Last bottle is at 645 and then cereal  and in crib at 730. They take a nap at 930am and at 230. He naps for 45 mins and she naps for 1.5hrs. I would like to be able to keep them at four bottles.
