Hi. Just sharing this in case someone else going through the same thing and this clicks.

When my baby was one (now 14 months) she started vomiting multiple times a day, often after meals but quite a lot when she was put down for bed. She wasn't ill with a fever or any pain but during the time was teething. We put it down to a tummy bug for the first few days, though she was eating fine and then went to the Dr who said there wasn't anything wrong and that it was possibly just solids and we should go back to puree. After another few weeks of puree foods and no improvement we went to the Dr again who suggested allergy tests. By this stage was already trying her gluten free which seemed to be reducing the vomiting.

Anyway, one of my mum friends asked me if anything had changed around the time she started vomiting and I clicked. She had gone on to level 3 formula. I rang the formula company who said that the level 3 is a totally different make up than the level 2 and the representative suggested I go back to level 2 formula. Two days later and the vomiting completely stopped and now she eats like a trooper, lumps and finger food and hasn't been sick since.

Sorry this was so long, message was if your child is doing a similar thing that started when you went up a level in formula, go back to the level before.
