Mason is 5 months old!!

I can't believe my boy is 5 months old!! On Thursday he finally rolled over and yesterday he rolled over twice but hasn't done it since. Maybe he's just not a big fan of it. Or maybe he hasn't quite figured out that he can go places if he rolls (other than his scooting around in a circle while on his tummy). He is still a very happy and smiley baby and sometimes when I kiss his cheeks and neck he ends up screaming because it tickles too much. He starts out laughing and that turns to screams :) We haven't made any real progress with solids. The last two times I tried he ended up gagging and was fussy and still needs more practice with using his tongue to push it to the back of his mouth so he can swallow it rather than spit it out.
