anyone tried this? does it help loads? my LO has reflux quite bad since about 4 weeks old (shes now 12 weeks) we are currently mixed feeding breast and aptamil stage 1 but i would like to change to aptamil anti reflux as this is getting a bit ridiculous changing her clothes every 5 minutes! anyway has anyone had any positive experiences with this? or negative? does it make babies constipated? can i use it alongside breastfeeding? and also i have tommee tippee closer to nature bottles with vari flow teat would i have to get a completely new set of bottles with fast flow teats?? thanks x
