Most of the bars and restaurants at Madrid Airport offer some sort of Children's menu and the terminal buildings try and offer as much as they can for families to make their travel as stress free as possible.
There are also self service cafeterias which make it easy to cater for children as they can select as much or as little as they want. But if you are travelling on a budget keep an eye on the prices as airports in general have a bad reputation for over-charging for food. For example a small bottle of water or can of fizzy drink is double the normal price, and a cheese filled baguette can cost in the region of €6,00.
Iberia has an Unaccompanied Children's Lounge on the first floor of T4.
There is also a new free indoor children's playground here in the boarding area for children up to 6 years in the boarding area of the T4 (nex to the VIPlounge). It offers a large playground with slides and ballpark. It has kitchen, toilet and rest area with cribs, baby baths, toilets (adapted for children) plus changing faciities with nappies, wipes, soap, towels,etc).
This indoor playground is open every day from 8.00 to 20.00 and there is another similar room located in the boarding area on the first floor at T2 (next to the nursery), but it is unsupervised and you need to keep an eye on the children yourself.
If you are taking your own pushchair on the flight, once you have checked it in you can make use of the free baby stroller service which is provided in every terminal departure area where you can use one of them until you board your flight. You leave the wagon at the departure gate as you go through to the plane.
There is a free nursery which is permanently staffed. You have all the amenities to bathe your child, change nappies and heat up food.
There are cots if your child needs to sleep or a play area to keep them occupied.
There are two nurseries: one in terminal 2 in the boarding area of Zone C and another on the first floor of terminal 4. Both are open every day from 08:00-20:00
