DS is bottle fed on Aptamil. I noticed yesterday in Tesco that Hipp Organic and Heinz manufacture formula milk significantly cheaper, in fact Aptamil is the priciest normal 'first milk' on the market and wondered if its case of you get what you pay for? I think I started on Aptamil because it mentions 'inspired by breastmilk' on the packet but really are they are all the same? any thoughts other formula mums?
