[mad4myboys]

ds2 is 6 months and has ongoing trouble with his tummy and gets alot of wind. i want to gett of drbrowns as am going to stop using sterilisor and deapite thelittle brush i worry about them not being clean enough as he is on neocate whichis hard to clean off! he had alot of trouble latching on all bottles but these, so which should i try now? he doesnt like flat/ortho teat

I tried every bottle as dd had colic. Tommee tipped closer to nature worker well. I did sterilize thou.
