I've called the poison control center a few times in a panic with my firstborn; turns out babies eat chapstick/ hand lotion/ diaper cream, ummm... a lot. Main point is that unless it's got some kind of prescribed active ingredient, most household cosmetic-type stuff is just gonna give them the shits at worst. But feel free to call them at any stage if you want reassurance directly! Take it from me, they're used to dealing with panicked moms whose LOs have gone buck wild on the diaper bag.
I love being a mom, personally. It's the most exhausting and by far the worst paid job I've ever had, and it makes you excruciatingly vulnerable in ways you couldn't have imagined. Also there are no days off, ever. Or toilet breaks. You have to deal with people motorboating your crotch at the grocery store, because *those* people came out of it. You get snot rubbed deep into the fabric of your favorite bedshirt, while they simultaneously poke you in the eyeball
and twist your earlobe, at 3:17am, because apparently that makes them feel better. You worry more than you previously thought yourself capable of. There's an upside in here somewhere, I swear- oh yeah, the doofuses themselves
God love 'em, the little goblins. They're still worth it. But anyone who tells you it's easy either has a nanny or is a fucking liar.
