OMG! Your siggy pic is freakin adorable!!!
I have a question for you.  What size tux did you end up ordering for Max?  I have to order one for Caleb and my SIL-to be picked one out on a website.  Their size chart has this disclaimer that the measurements listed are for the clothing, not the child's body.  Well that's helpful!  Plus they have a $15 charge just to exchange something!  My mom measured Caleb to fit into a small which, on the website, is for 3-6 months.  Yeah....I don't think so.  Caleb is in all 18 month stuff.  Things fit pretty well, so I have no doubt he'll be in this same size for the wedding.  I'm guessing I'd get an 18 month size tux?  What did you do?  TIA!

I ordered Max one size bigger since the wedding is still 3 months away. He is in 18 months as well and the Ebay seller that I ordered from was in S, M, L, XL. I ordered Max a XL which said it was a 18-24 months. It looks like it may be a little big, but my mom can take it in if need be, plus I am a pro at shrinking things )

If it helps, Max is currently 25 pounds and about 27.5 inches long.
Good Luck.
