help a FTM out!

Gemma

Okay I'm a first time mum and this may seem like a rediculous question but the just of it is my little girl almost 19 weeks has never really been a baby that vomits (the occasional spit up once in a blue moon) but the past week or so she's been being sick alot not huge amounts but more than she usually does is this something that I should get seen? Also anyone have similar experience with this? Thank you in advance
