Rice cereal in milk

Hailey
My daughter is 3 1/2 months and usually eats about 4 oz every couple of hours. (Formula fed) I have tried stretching her schedule so she can go longer until her next bottle, but it doesn't stay consistent. At night, she is still getting up every couple of hours to eat and then falls right back to sleep. Has anyone tried a little rice cereal in their baby's bottle before bed? If so, does it help them sleep a little longer at night? I'm going to the pediatrician on Monday but I always like getting opinions of other parents to!
