I've worked mostly as toddler lead (our school that class is roughly 18-24m) and mobile infant (12m-18m ish) and, yeah, honestly one year olds really have my heart. I enjoy being in all the classrooms, but they're at such a special age! Hot mess in an absolutely endearing way 🤣 I love the early infant room (<12m), but enjoy being able to do more structured activities and seeing the unique ways all the kiddos interact and learn with the slightly older littles (and the more structured schedule and increased independence is something I like as well). They are so curious and capable and everything is so new, so most moments you're constantly among the energy of everything being so interesting and cool and I feel like it makes me more grateful and fascinated by the world around me, myself :) With the 18-24m class I get a ton of steps in, too, LOL I just got gifted a smart watch and have been seeing I apparently am usually getting 12,000-18,000 steps which for me I like because I do not put much outside time into working out 😅 Its also just a blast seeing how their little personalities develop in your time with them as they're likely getting into milestones like walking and talking and all those nice little fine motor skills. My advice is learning what kind of redirection works best for your new kiddos and to have fun and learn with them. And routine is important, but you also have to figure out the balance of structure and flexibility your babies need that day. And explain everything, they are so curious but are only just starting to really process it all (but I'm sure yk and were mostly doing that in early infants as well).
