DD2 (18 mths) spends a lot of time playing independently outside. She has complete access to the back yard as long as it's not raining and I keep an eye on her, but until she comes to get me I leave her to it. Mostly she wanders around picking leaves and grass to feed the bunnies and 'talking' to herself. Lol When DD1 is home (7) they both go out the front yard until I call them in, pretty much. If it's raining, they disappear upstairs to play together. It's wonderful that even though they're such different ages they still play together. <3
