Thanks SnowChickie.
Ethan is taking after his father too in the bottom noise stakes! He has plenty of wind (both top and bottom). He is actually quite lazy bringing up his wind (just like his big bro and uncle) so he has Infacol drops every feed. I'm hoping that he will be able to stop them soon as he seems better at bringing it up now.
I'm going to see how this Guardian formula goes as it's only $12 a tin! Hopefully it works.
Once again Thanks
