Can I take pureed food on a flight for my 7 month old? Is it counted as a liquid?

Nope. We've carried all sorts of purées and it hasn't been a problem. Some airlines are particular about liquids though - not more than. 100ml per bottle

Baby food is exempt from security regulations for other liquids. So yes you can take pureed food on flight

thanks

Yes, you can bring pureed food for baby on flight.
