Keep in mind that the Goya paintings and drawings are dark and scarey, which could be a good thing or a bad thing depending on the age and temperment of your child. Our kids loved the huge and beautiful Italian Renaissance paintings.
For 14.40€ you can buy a Paseo del Arte combined ticket which lets you skip the lines at Thyssen-Bornemisza Museum and the Reina Sofia Arts Centre as well as the Prado. The MadridCard also gives you free admission, but you'll be hard pressed to make it a good value with kids in tow.
If you don't buy advance tickets, keep in mind that the Murillo (South) entrance often has shorter lines than the main entrance.
There is a large playground between the Banco de Espana metro stop and the museum. We recommend running your kids around for a little while at the playground to wear them out before you enter the museum.
