Growing Up Fast

I know its schmaltzy to say, but Ingrid is just growing up so fast it's scary! She's 18 months and is so incredibly perceptive of all things going on around her. She's on the cusp of talking, where we can't understand her but she knows exactly what she's saying. Her vocab recognition outpaces her pronunciation....we say 'window' 'moon' 'hammer' 'umbrella' 'boat' and she's quick to point them out. I've no frame of reference for how things should progress, it just seems to me that its all going so quickly.
