Baa baa goats milk

Having a trial run with goats milk for Poppy. I put her back onto cows milk, mixed with formula, and she has started having bad nappies again. Health visitor wasn't too helpful about cows milk intolerance last time I tried, so not bothering speaking to her again! Goats milk is worth a try, apparently it's all a bit trial and error if they won't get on with cows milk, but whatever. Just want to move past sterilising bottles and making up formula!
