Thanks everyone. I thought that might be the case. Both my DF & I have a history of asthma (my DF was so bad as a child he went to asthma camp - who knew they had such a thing) so from what I've read Brock is likely to either develop that or eczema. He's been rashy from early on & he's been a happy chucker from birth but the MCHN & GP aren't too concerned about it as he's developing well.

Just wish I found it earlier, but being determined that I was going to breastfeed I didn't do any research whatsoever into formula therefore was not at all prepared when BF didn't work out and just grabbed something in a hurry on the way home from hospital for his top up feeds.
