Happy Chucker Formula??

Hi

Need some advice. My daughter Allegra has been on NAN Gold 1HA since 9 weeks (she is now 16 weeks) and has been bringing up a lot of milk after every feed (even an hour after the feed) I am forever cleaning this up and she is always in a bib to try and catch it before anyone wears it. She does get upset when she brings it up but once its out she is fine and she has no other signs of being in distress.

My clinic nurse suggested I try Novalac Reflux formula and she has been on this for a few days now. Throwing up has reduced but need to know:

If anyone else has used this formula or any other one which has helped to keep the milk down?

I would have like to continue with the NAN but I need to make it thicker. Someone mentioned on here a thickener can be added, whats the name of this and is it just added to the bottle?

Thanks
