My son is only 9 months old so I know I've got quite a while. I was thinking about starting him in some sort of extracurricular activity next summer though. Early gymnastics was my first thought because he's built like his dad, short and thick and muscular. However though he won't be old enough to pick one himself yet we are super open to him pursuing ANY activity he loves. Sports, dance, art, music, anything he's passionate about. So if he decides in a few years he doesn't like what we sign him up for we won't be hurt lol. But we want him to do something he'll enjoy as a toddler! If you've signed your toddler up for some sort of extracurricular activity what was it and how did they like it? TIA!
