i hope this doesn't sound ignorant but do cf babies have a lower birth weight. my eldest was 8 pound 1 and i assumed my next baby was going to be heavier. i was "dissapointed" when i found out he was 6 pounds 11 'cos second babies are usually heavier than the first. bearing in mind we didn't know joe had cf until he was 6 yrs old.also if we had known he had cf at birth (he just missed national screening by approx. 2 months) what treatment would he have had from birth. he showed no sign of any problems til he had pnuemonia just before his 6th birthday. ( in hindsight his nappies used to stink to high heaven<img src="i/expressions/face-icon-small-smile.gif" border="0"> the nappy thing just crept up on us and we thought it was normal<img src="i/expressions/face-icon-small-frown.gif" border="0"> we would never have considered taking him to drs. because he had smelly nappies!!!!!!!!!!!
