I also transit LHR frequently and fully agree with this. BA is where you want to go, their kids play area is well-stocked and in a separate room behind glass so your kids can get loud without bothering anyone. They have a wide variety of food options from either the buffet or the menu. Their showers are sub-par compared to AA, but I think the other components more than make up for it.
