It will go by fast. The first 3 months of our twins were trying to say the least but now they are 18 months and there is nothing better after a long hard day than hearing in stereo "da da da da da da da" when I open the back door. My wife says they have figured out about the time its getting dark I should be home soon and start looking out the back window every few minutes. She says they finally hear my truck (cummins with no muffler) and make a b-line for the back door no matter what they are doing.
