Toddler has stomach bug🤮🤮🤮

Ok ladies - it’s official. My poor little man has an upset stomach. Has vomitted three times since 6:30... he only wants mommy and I totally am here for him- it’s so sad he’s feeling so bad ... my question is- what happens if I catch it? Knock on wood - he’s had upset stomachs and I haven’t caught it before but it‘ s a whole new ball game now that I’m preggo.
