Handle With Appropriate Precautions
Babies are a font of... well, most everything. If it's a bodily fluid, they probably eject it and at surprisingly high speed with spectacular accuracy (or inaccuracy, depending on whether you see it from the point of view of the baby or the recipient).
Technically urine, feces, saliva, sputum, nasal secretions, sweat, tears, and vomit don't qualify as biological waste unless they contain fluid blood or a known infectious pathogen. Try telling that to a first time parent changing a diaper, though. On the plus side, in terms of proper waste handling there's already disposable padding added for absorption, and the waste comes packaged in a leakproof (theoretically) container. Of course, you might be the cloth diapering type, in which case we recommend you set your at-home autoclave (the washing machine) to the sterilization cycle for at least 30 minutes.
