Today I am babysitting a friends 5 yr. old and it feels like I still only have 2 with me, Zach is so good, has good manners and says please and thank you. So far this morning we've painted, made a card, ate, done yoga, played the memory game, did legos, puzzles and now although my 2 yr. old looks tired she still is fighting the nap but the good thing is I didn't have to supervise every single activity because the 5 yr. old was teaching my 2 yr. old little things she doesn't know and I believe she may have even taught him a thing or two:) So introducing older kids to your toddler is helpful for them to learn things they may learn better from a peer.
