My daughter was two when my son was born and she went through a rough transition period. Luckily, she got a Graco baby play set around this time, which included a pretend car seat, high chair, baby backpack, baby bottle etc. She adored carrying her dolls around and feeding them the way I was feeding and caring for her new brother. There were so many options for her to play with that it took a long time for her to get bored. Her brother is 2 now and we are STILL playing with that stuff almost two years later! I guess that shows that women really are born to be nurturers! :-)
