I am posting for my sister. She has a baby 5 months old. She is exclusively breastfeeding and all going great. She has just been told she has terrible arthritis (has been having problems for a long time) and since having a baby has got really bad. She has to start a very strong medication to hopefully improve things for when she gets older, but cannot BF on this. She is really sad about stopping BF but feels that this is for the best. Anyways . . .the thing is none of us know much about formula feeding as all BF!! Obviously when at home you heat it up etc but what do you do if out and about? For example not near shops or cafes. Do you take hot water in a flask and add the formula? Or take it ready made and take hot water in a flask to pour into a bowl to heat it?? God it sounds a nightmare!! Please give us some tips!!! Thanks! xx
