I'm gradually stopping BF and moving over to formula. DD is 6 months and 1 week. I was using Aptamil stage 1 for the 2 feeds a day that she has formula but now DD is over 6 mnths I changed over to stage 3 (6 months + milk with extra iron). DD really seems to hate it and screams blue murder during feed and almost exactly 3.5 hours after a feed of stage 3 (but not after a feed of stage 1).
Can I just keep using stage 1 or should I really try with the "6 months +" milk and, for example, try different brands? We're trying BLW so there might be an issue with how much iron she's getting from solids...
