Seems like it would work, but she would never have 4oz with dinner. And, if she did, she would never have 4 oz an 1.5 hr later. Maybe she would surprise me, but seems like a lot of food/milk in a 2 hour timespan. I am going to start toying with it and see what works. Right now at bedtime, she really only takes anywhere from 3-4oz, in a bottle.
