Just as tylersmommy said, I would cut down on her solids early evening so as to make her hungrier for her bottle. Or you could also try doing the solids at 5pm if she is hungry and then nothing until her 7pm bottle thus making her hungry enough to take the bottle. As well maybe also to fiddle around with things even more, give her solids at 4pm then nothing until her 7 pm bottle thus making her really hungry to take it. I haven't had a df since 14 weeks and this helped adjust her taking more food during the day. Ella's routine is pretty close to yours and this is what works for us.
7:30am bottle 6-7 ounces
9:00 am 1.5 tbsp rice or oatmeal, 1/4 jar fruit or veggies 1-1.5 ounce formula with cereal
10am-11:35 nap
12pm bottle (5-7) ounces
1pm solids (just veggies or fruit, no cereal) 1/2 jar-3/4 jar
2:30-4:00 nap
4:00 bottle 6-7 ounces
5:30 3 tbsp rice and oatmeal mixed, 2-2.5 ounces formula, 1/2 jar veggies
6:30 bath, massage
6:50 bottle 6-7 ounces
7:00 bed
Sleep till morning, no df or nightwakings.
Hope this helps
