My soon to be 2-year-old daughter is having a 'I wish I was still a baby' phase. She gets under the floor play mat and makes the same baby sounds as our 6-month-old. She even manages to get inside of the jumperoo, but then whines when she can't get out.
Poor baby! She has it worse than my other children did when a new baby came along. Where does the time go? It seems like only yesterday she was a little baby herself. I have to remember she is no longer a baby, but a toddler.
