@Corin this makes so much more sense!! Unsure why we didn't think of that 😂 thank you
Haha, it's okay. We got used to doing it that way because we have carobel to thicken and needs to be drunk in around 15 mins once added, so it was more habit than anything, but hope it helps!!
When my little one had this I had all the same problems it kept clogging the bottle! In the end we mixed it up with water and then gave it during feeds with a calpol syringe x
When we used it we made the milk and added the gavisgon just before drinking after reheating the bottle and never had any lumps x
