My 6 year old has strep throat and been given penicillin liquid. She's had her first dose but she was crying so much and gagging a lot of it came back out. The label says it has to be taken on an empty stomach or 1 hour before food. She's due another dose soon and I'm wondering if I can mix it in a drink or some yoghurt but also worried it could stop the medicine working properly. I did Google it but got some conflicting results so looking for some advice from anyone who has been in the same situation. Thanks
