You sound like you're up on the medical advice angle, so I'm not going to go there at all.
If it's NOT projectile, our son was that way. Wheeee. He was also a REALLY big eater, and any of the normal "tummy bump" or "bending" him could and would set him off. That's in addition to needing to be burped really well. (We found burping for about 10-15 minutes after each feeding was what he required. Most of our friends' kids only needed a minute or two, but I have no idea what the "norm" is.)He spit up less and less as the months went by, but yep! even just the act of handing him to another person could set him off. Now that's love. "Oh! Can I see the baby?", then me cringing, "Ummmmm....well??? He's a spitter, so what would offend you the least?"
If it's projectile, that's a whole 'nother matter (of which I have no experience), even though it CAN fall into the range of normal. Your doc would know.
What I did was carry a backpack with all the usuals +
- A few shirts for me
- A few changes of clothes for him
- babywipes (of course, but they work great on little drips on clothes that don't warrant a full change, and on hands, and faces)
- A box of big ziplock bags (for garbage & laundry)
- Makeup (because if you've been sweating while doing this in public, and wipe off with a babywipe...so refreshing...it's great not to look like a raccoon afterwards;)
- I also took a lot of showers...I'd even just leave my son in his car seat (in the bathroom) while I'd pop in and rinse off. I figured, hey, if he can be in it in the car to keep him safe...2 more minutes in the bathroom is nada.
Don't get trapped in your house!!! Baby spit up is in a whole other realm than vomit. Rather like the screaming & crying thing. If (for an imaginary example), my husband was screaming and crying I wouldn't take him anywhere, or would leave immediately. I can't count the hundreds of places I been with my wee one in a fit of temper. Babies do both, spit up and scream like banshees. In fact, they also go to the bathroom in their pants. Different rules apply.
You'll be surprised both at how quick you adapt, and the number of looks (the, "Oh! I remember when...." looks) you'll get from people. Jerks tend to be few and far between. Once in a restaurant when my son DID spit up all over the table (at a very nice place to boot!) I got a huge laugh from the waitress. She had four kids of her own, all grown, and can't wait for grand babies. We even got free dessert.
One trick, if it's all over your shirt, is to wipe it "clean" with a (or a series of)babywipes, put your new shirt on over the "cleaned" one, and then take the other shirt off. That way you can change in parking lots, or your car, or the park, etc., and not have to search for a bathroom.
((If you don't know that trick, you
1) put on the second shirt like normal.
2) pull your arms out of both sets of sleeves.
3) put your arms back through the arm holes of your 2nd shirt, but not the first, so the first is only on around your neck under the second shirt
4) pull the first shirt off through the neck hole of the second.
5) Use a babywipe on any skin that got wet through your shirt & Voila! Ready to attack the day again, and you smell nice too.
* * * You can see why it's important to clean the spitup off the 1st shirt....OTW it just gets all over your clean shirt, and then your hair. ewwwww, yuck. Got distracted and BTDT* * * ))
Soooo glad that stage is over, :)
