Hello, I’ve been using infacol with my 3 week old, place the infacol at the back of their tounge and put the bottle, Breast, or Dummie in their mouth so they suck and it will ensure they swallow the infacol hope this helps ☺️
I mix mine in the bottle works a treat and if you’re using formula it makes the milk silky really helps with reducing any bubbles x
I'm unsure about it going in the bottle although it says its meant to go on the back of their tongue not under it as there's less chance they spit it out I believe
