@Amy thank you but he can’t have premade unfortunately is on formula from the doctors
There’s a good group on fb which will help with the best bottled water to use and lots of useful tips/ packing lists etc! https://www.facebook.com/share/g/19kN7Eomzf/?mibextid=wwXIfr
For formula, I’m taking some pre made bottles over for during day, in regards to making them up I’ll just boil bottled water
