My LO has a cows milk protein allergy but I suspect she has other allergies/intolerances. I started weaning her and have been giving her a new food every 3 days. She did fine with banana which was the first thing I have her. I felt like her stomach got a bit upset after giving her avocado so I stopped and gave her a break for a couple days. I then gave her apple for 2 days. She started to get hiccups and since this was one of the symptoms she had when she had cows milk I assume she can't handle apple. I'm now giving her oats. 5-10 minutes after eating she sneezes a couple times and coughs for a bit. I'm not sure if this is an allergic reaction or if she's just getting used to solid food. It's a bit confusing because I don't know if it's all a continued reaction from one thing I gave her or if she really is allergic to multiple things. Her stools have been mucousy but again I'm not sure if that is normal when you start weaning
