The time has come! The twins are sitting up!! Collier beat Anne Collins by a couple of days, but thats ok because Anne Collins beat Collier when it came to rolling over! Now they can REALLY play together! I just sit a toy between them and they play away! Anne Collins is alot more aggressive. She wants the toys to herself! She is very very playful. And Collier is very laidback and observant. She watches Anne Collins, but don't get her wrong, when she wants something, she lets you know it! They are so much fun to watch! At 7 months, they already have such a great sisterly bond!
