Persevere with the Comfort - I bet you wont be too disappointed. I too had a very colicy little boy and I met with the opinion that he would simply grow out of it and I shouldn't change his formula.. I was using aptamil at the time! One day when I was in tescos I saw the Omneo Comfort and it sounded perfect for William so I used my mommy sense and went ahead and put him on it.
For about 2-3 weeks we had very smelly, green nappies and lots and lots of egg smelling trumping which I was told is normal and almost immediately the colic started to vanish so I persevered. In next to no time William was transformed. He hardly spat any milk back, we had no back arching, crying or any sign that he was in any pain. The wind could escape and started to become less smelly and became "normal" amounts for a LO.. I have to be honest I would recommend Omneo Comfort to anyone who has a LO with colic or digestion troubles - its been fantastic for William.
I will say is its certainly best made up the night before as I mentioned. As the instructions say its best made with fairly hot water so its difficult to use as some mommies do where they take the bottle of water out with them and mix in the formula as the feed is needed.
I also changed my bottles soon after this to the Dr Browns Bottles - now called B-Free. They are briliant too as they stop the LO swallowing so much air as they feed and they make it wasy and smooth to drink the formula from the bottle. With Omneo comfort I found that I could still use the number 1 teats and have worked up through the stages as normal.
http://www.babybfree.com/Its good to hear you are using colief.. be sure that you dont add it when the water is too warm or it can stop it working. I used it for Woo even with the Comfort which has already got reduced Lactose in it and was really pleased with the effect it had.
