Our twins are 19 mos, we want someone who will spend time playing, drive and take them out to playground, library, parks etc when weather permitting. Someone to actively play and talk and show interest in helping them learn. A little bit of light cleanup of their play area in the house would be required. We would be looking for part time 3 days a week staring now, say 8:30 to 1:30, then by May have it 5 days a week 8:30 to 1:30. Our 3rd child is due June 12 and would likely keep with 5 days a week until early into 2013, then drop back down to 3 days a week after that.
