Tummy aches

My poor little Cruz has had a bit of the flu the last few days. He's been throwing up and more fussy than usual. He seems to be coming out of it now, but it wasn't fun to see him all sick. Part of his problem might be that he eats too much at once as well. I'm trying to burp him more often while I'm feeding him now to try and help. It seems to be working - or he's getting over the flu. He can't tell me, I can only assume! Either way, he seems healthier today!
