I have 2 in that category one is 12 months not walking but feeds himself, very happy to go outside and just crawl around hates to be restrained in any way so no strollers or wagons just wants to crawl and goes up and down stairs by himself so I don't have to carry him thankfully as he is 30 lbs, the other one is 18 months, walking, a few words , eats be herself, up and down stairs no problem, those are the pros...... The cons ..... Both need total help getting ready for outside and although I'm working on the 18 month old to help clean up right now it's mostly hand over hand while she's screaming no. They don't share. I like to bring them in at one cause you dont have to undo another providers ways and hopefully they are with you longer .
