My son Ikaia is almost 16 months and has been on Isomil 2 advance soy formula since he turned 9 months old. I have tried introducing milk to him but he WILL NOT drink it. I have also been trying to wean him off bottles entirely. He drinks juice and water from his beaker cup but when it is time for bed, he will not sleep w/o a bottle, and it has to be his formula. I tried mixing the two (milk & Formula)but he will not drink it mixed. And occasionally he wakes up at 1 or 2 am for another bottle. He eats solid foods no problem, and snacks on fruit, veg, crackers, etc... but lately, and I was wondering if this has anything to do with his formula, he wakes up on occasion @ 1am and cries for 10 minutes or so then takes his bottle and goes back to sleep. My husband thinks it is gas, but I do not know what to do and my neighbors are ready to kill us (because of his night cries)...HELP ME
