I'm realizing that purchasing all the props, furs, backdrops ect for newborn sessions can really add up.
I've also realized it's practically impossible to avoid "accidents" shortly after removing the diaper to get those cute "bare butt baby" shots. Is their some hidden secret im not aware of to avoid having all of your expensive props & furs covered in baby urine... Or worse?
Part of me is afraid of investing the 60+ dollars in a fur which is going to be ruined within the first 15 minutes of a session.
Also, where are some good places to purchase props for newborn sessions (aside from Amazon)
My understanding is that especially for boys, when cold air hits their penis (and that's a new sensation), they pee. Which is why new parents often get peed on when changing diapers.
My advice....tell the Mom ahead of the shoot about this issue. Advise her to give junior a little bit of experience with this (being exposed to the ambient air where you're shooting). Partially this preps for the shoot. But it's also a good way to minimize diaper rash (and that's a point to stress with Mom so there is a reason for her to want to do this a lot before the shoot).
As others have pointed out, putting down a liner or tarp is good. You can go to Home Depot and buy a clear, transparent plastic drop cloth that is about 6x10 for about $5....it's a very wise investment (once had to use one when in the field and I got got in a downpour with no cover)...so buy a couple of them. These things are packed up very small (about the size of a small burrito) so easy to throw in your bag.
As for props, most suburban neighborhoods with have stores where people are recycling their baby stuff (no more babies on the way and they've got 3 strollers, a mess of onesies, and a ton of toys). Anything you buy this way, be sure and disinfect after purchase. Props for baby shoots run in to a bunch of categories. There are the standard cliche (something that looks like a white sheepskin/wool rug), toys for baby to be occupied (plastic blocks to teeth on, animals that are cute, wooden blocks), props that might have some connection to the family (they have a dog, you have a toy dog....Dad likes to fish...you have a toy fish....Mom went to school at the local "U" and you have a onesie in the University colors) and then props that are child safe but will fascinate the baby....a sunflower, a ribbon and bow. It's up to you to decide how much crap to acquire. If you live in a University town or one where there are 1-2 big schools, it's worth it to have some sort of University-related prop (school colors, mascot, football with the University designation, etc.). It's worth it going to a petstore and looking at some of the dog toys that are weird shapes, made to be chewed on, washable, might have holes in them to hold treats--it's not that you're going to stuff smashed carrots in it, it just might be something that fascinates baby and gets them focused on the toy rather than why Mom is standing right there but not holding her.
I'd also acquire a big piece of lace and a piece of white curtain (you can get them off of Amazon for just a couple of bucks.) I would post a shot I just took of a nursing Mom using just such a piece of fabric but it would qualify as NSFW I'm afraid. Anyway, the point is you can use the cloth/fabric to cover up distracting items (the baby's diaper, the mom's pants and maybe a little bit of weight left over from the pregnancy) and just expose the babies head and arms, the Mom's face and shoulders and a breast. Plus, the white fabric serves as a great natural reflector...you put the baby down on that and you get nice soft flattering light all over the place, you minimize the need for speed lights and strobes (which some babies don't react well to). It's white--so it stains. But you could buy a 4-piece curtain set for probably $12 dollars and then you've got 4 white backdrops, ground covers, drapes.
