Re: 2 year old son with a hard tummy?
Ummmm, sorry to have to give you this response. I truly am. I hope like mad that your little guy is just plain old plugged up.
What you describe is exactly how my cousin died. His father was squeezing his tummy and my brother's tummy. My brother's tummy was squishy and gave in. My cousin's tummy was hard with no give. My cousin turned out to have a large tumor in there that killed him shortly thereafter.
I would feel horrible NOT telling you this because if you don't get him checked out, you can't rule this out. Please just go get him checked out so you can be sure it's nothing and move on.
I am sorry to say these things, but if I didn't I would feel worse. I have a son as well, so I know what it's like to be afraid for their well being.
