All great pictures! I love the kiddo shots!
There are a ton of good cameras out there... I am a Nikon DSLR fan, and own too many... My main axes are a D90 and a D7100. Both are older, but very reliable. Nikon's newer D3300 has lots of good reviews, 24.2 megapixel, and comes with a 18-55mm lens. About $450.00 +/- My step daughter just bought one and loves it.
