my dd was 21 months when ds was born. she stayed w/ my mom, then was brought to the hospital to meet her brother. funny (cute) story - my mom and dd came in the room, dd was SOOOOO mad at me. She wouldn't come over and say hi to me, would barely look at me. She was fine w/ dh, and LOVED her new baby brother. But boy, she was pissed at me for not being home that day! well, excuuuuuuuse me! 

They came in after school to see their new brother.
