Try Googling open source stock photos you may find a few to use. :) I found some good ones for a site I built for a client recently, I found the handful I needed for her site. Also search stock photos for bloggers on Pinterest, I see Tons of pins there.

On Pinterest most bloggers just use photos and give credit and link to the source.
I personally ask to use photos.
Just make sure you link to the source, that is the most important when using content. :) Most bloggers love the sharing, its helps all of you.
You may want to see if you can connect with some local photographers in a facebook group or meetup. You may be able to work out some trade, a photographer will throw in one of your pictures at a newborn shoot or the like. I would if I did enough newborns and babies but I do a handful a year or so.
Try to seek out people with nurseries local and see if they will let you take pictures. Through friends and such, 'network' to find those babies rooms if you know what I mean. Wing it and post an ad on Craigslist, say you are looking for nurseries to photograph your work. Give them a free picture for letting you shoot a few quick images. You never know...
Side note- Id do a picture for you. I can set it up with my jars all cute and make a baby set up. If your willing to send me something I'll do it. :) 8x10 or smaller will work. My photo boards are big enough for pictures like that.
I will also blog it as well. ;) You can too, content score! ha ha
