Hello everyone again, Chris from Uk.
 I forgot to add that the baby with pyloric stenosis only had breast milk and
has become quite fat in the two weeks since surgery! The most pleasing thing
was that his mother originally at booking was undecided about how to feed but
was probably going to artifically feed. With the right information she made
her choice and said how glad she was that she was breastfeeding him as it
would help him to recover more quickly and how close she felt to him. Great
isn't it.

Thanks for all the reply's I have had,   Chris.
