He's how old?

I'll be the first to admit that I had no idea how quickly the little one would/should grow. He was still a little one after month one, then month two. Then, a growth spurt hit and sometime during month three he got much bigger very quickly. Ever since then I have been dealing with, "Aw what an adorable baby! How old is he?" "He's three months old" "WOW, what a big baby!" And again at four months, as he kept growing, "He is a big baby! His daddy must be a big guy, right?" Truth be told, his daddy is a big guy, and apparently Isaac is going to be big just like daddy. At five months, "Whoa, he's only 5 months? He's going to be a BIG boy!" And now, at six months, it is clear that his growing is NOT going to slow down. My six month little guy is a whopping 20 pounds 4 oz and 26 inches long. He's a little heavy for his length, but the Dr isn't concerned since he is just becoming mobile and is expected to lean out. His weight gain has actually slowed down since his 4 month visit and his length is catching up. His growth is amazing, but I enjoy my big cuddly bear. I just hope he walks early because if he does get much bigger I won't be able to carry him much longer.
