i've been fedding my DD a tablespoon of farex for 4 days now, around the 11am-12 mark, and this morning i fed her 1 1/2tbs and she's been eating all of it. is it too early to mix it with a fruit of vege? should i wait a few more days? i can't use banana for her cos my family have a history of asthma, and just in case she has it (knock on wood!) she can react badly to it. so i heard apple and avocado is good. do u boil them? and do u use it in place of mixing it with the milk? sorry i've asked alot of questions in the one thread thanks, Angela
