How do you feel about your baby's (babies') first words?

What were they?

My son has yet to say mama and that makes me a little sad... but is saying some fun stuff like spoon ("'poon"), hi dad, ball, bird, squirrel ("quirl"), box, tree ("tee"). That makes me proud.

All milestones seem to come with such mixed emotions (he's growing so fast, I'm so proud!, what if xyz?)
