Hi Jennifer! Just express your milk for one feeding to see about how much he is eating. Usually the baby is getting twice as much as you can express but he won't need that much because the cereal will fill him up. This is also how you can see about how much milk he is drinking. All babies are different and so you really can't compare him to others at his weight and age. He is his own little person. You will understand more about what I mean about this when you have another baby!!! I can tell you that the cereal feeding will help the acid refluxe a lot. Try it at night first. He will 1. not be in pain having the acid refluxe at night and 2. be full for alonger period of time resulting in sleeping better. Which means you will actually get a full nights sleep!!! Hopefully anyway.
I know how you feel about nursing. I felt the same way with my last baby. I wasn't able to nusa my first 2 for more than 2 weeks due to meadical resons and surguries that I had to have but it was different with my last baby. She even enjoyed it. It's a real bonding time and a special time that only a child and it's birth mother can share. It's a beautiful and moving thing. Just remembering it now brings tears to my eyes. I had forgotten! She is 19 months now and I started drying up when she was only 5 months old. I haven't nused her at all scence she was 7 months old. Wow! It has been awhole year now! My how time zooms by.
Good luck! Let me Know how it goes.
