I just thought I'd give a little update after 5 days of 3 bottles/day. Kaitlyn is doing great! She is still only drinking 21-23 oz/day, but that is typial of what she normally drinks. It took a couple days of figuring out when and how much to feed her, but she's doing great and actually sleeping better at night
She is also extending her A times which is making us shift her schedule anyways, so I think this was the perfect time.
Here's our routine (ideally):
7am - Wake, eat (8oz)
8:30 - Breakfast (2 cubes of fruit, 2 tbsps cereal) This could not be any earlier or else she wasn't hungry enough to eat, and then would not take her nap out of hunger.
9:30-11 - Nap
11 - Lunch (1 cube meat, 2 cubes vegetable)
1:30 - Bottle (6 oz)
2-3:30 - Nap
4 - Dinner (4 cubes vegetable and rice rusk)
5:30 - Bath
6 - Bottle (8oz)
6:30 - Bed
Thanks for all the help and information and encouragement.
