Round about now a lot of children will be enrolled in some kind of daycare or kindergarten. Make sure you have a good look around the place, and ask plenty of questions of the carers, management, and other parents, before deciding to settle on a particular venue. Daycare of this kind can be wonderful for socialising your child; teaching common play, the rules of society in a little microcosm (don't cheat or steal, get on with as many people as you can, etc).
Potty training may be coming along, or perhaps just starting around now - every child develops at a different rate. It's important to continually ask them if they need to "go" - they will, at the start, rarely volunteer this type of information. If you ask regularly, you're far more likely to be successful early on, rather than relying on toddler to tell you out of the blue that they need the potty.
