Sambuccol for babies

Hello mummies , I bought sambuccol for babies after seeing a very big improvement with my first born “immunity” when we started giving it to him when he was about 20 months old. So I bought the “for baby” version for my 2nd born. Seen mix reviews of it online, so I wanted to check with mummies here if there’s anyone who has given their LO sambuccol for babies aged 7 months and under, and if possible if you could share some reviews on it. Thank you in advanced!
