Hi, I wonder if anyone can help. My DS is 11 weeks old and for a number of reasons (please don't judge!) is now exclusively on formula. We use Hipp organic and he hasnt had any problems with it since we began. In the last few days, at some feeds only, he will look disgusted when you give him the bottle, but after a minute or so will start to drink normally and finish the bottle. He did this when he was only a few weeks old but had stopped until now. Everything is cleaned and stabilised before use and bottles made up before each feed. Any ideas? Thanks l!
