Of these, the only other one with a designated kids area is the Eventyr lounge, at the top of gate C after passport control, which means you can only access it if your flight is leaving from that gate (some but not all flights leaving Schengen). You can bring enough food or milk for your baby to last the duration of your flight, including water or hot water to make formula milk, and it’s exempt from the 100ml rule, although they may make you taste it at security. In some areas (like Gate C), there’s a 7-Eleven after passport control where you can grab supplies, but others (like Gate F) only have a vending machine, toilets and benches, so make sure you’ve grabbed everything you need before you head through to your gate.
