I like bringing them into care right after mat leave and they are generally pretty easy going I like watching them reach milestones ...like walking .... But then I'm not fond of the 16 to 20 months but I like the 2-3s as they are talking and singing simple songs and learning the alphabet and they are just more fun and they are doing things for them selves too like potty teak gig and dressing themselves for outdoor time ....
