I have a toddler (28 months) and an infant (4 months). I do love having conversations with my toddler, seeing her laugh, seeing her play, and watching her grow into a real human.
However, the infant stage, in my opinion, is a million times easier. In between the awesome toddler moments are tantrums, battles to get dressed, refusals to get into the car, etc. I love my toddler more than words. But man, do I just want her take longer naps sometimes!
