Okay mamas so I haven’t had to deal with this situation until now I think there’s a stomach bug going around because my little one just threw up twice randomly and a lot .. and two other ppl I know of their kids have been throwing up too.. what else can I give her aside from pedialyte? Yes, I’ll be taking her in if she can’t keep anything down .. but any recommendations/tips?
