My Grumpy Guy

My usually happy smiley baby has been a bit of a grump lately. Why? He has a pile of toys and two sisters that can't get enough of him. Then I noticed the snotty nose. Yuck!! Another cold? Really? Why can't this little guy stay healthy?
I then thought I should check his gums to see if he's getting teeth. Oh yeah! That's it!! His lower left tooth is breaking through and I think he's not liking it much. Hopefully it will come in quickly and he can be happy again!
