Growing up so fast

Will recently discovered he has a tongue... now he sticks it out like this all day long. it's really funny to watch him because he's fascinated with it.
These past couple weeks he's had quite the list of achievements!
sits on his own
started to eat solids
learned to self feed
pulls himself up to standing
added several consonants to his vocabulary
and uses toys to help himself walk

I can't believe how quickly he's growing up! Before I know it, he's going to be talking and walking... where did all the time go??
