I have three of them now. I've had my part-time son, Taze, for two years. He was only a few weeks old when his mom had to go back to work, and of course my own kids were in school all day, so he had my undivided attention. I probably never told his mom this, but that first year, I held him every day during his nap. I kicked back and caught up with my DVR, read a book, or even dozed off myself. We bonded, for sure, and we are still tight. I attribute that to all that snuggle time.
The next school year started and I gained Emma. Her mama is also a teacher (I only babysit for teachers and that rule is firm). Emma was about 6 months old when she started coming to play every day. She fit right in and we all settled into a new routine...most days. Emma is a year and a half now, and she came back to me today after being at home all summer, and it was like she never left. It seems like she was here yesterday, no exaggeration.
This year we have a new addition, Olivia, who will be two next month. I could not have hand-picked a child to fit in better with my first two. Whereas Taze and Emma grew to love all things Toy Story and dinosaurs last year, Livvy has no interest in either. So as long as she isn't reaching for the T-Rex, she is okay in their book!
If you're keeping track, next month I will have 2 two-year olds and an almost two year old. Luckily, I've never bought the whole "terrible twos" folklore. Ever since my daughter was young, I've always said that whoever coined that phrase hadn't yet survived a three year old! Nonetheless, my days are exhausting but I have some stories to tell.
