Natural History Museum London is nursing mum friendly. First off, admission is free and they have a nice cafe which many mums use when not crowded. They Also have a private nursing room with comfy chairs. Their changing room is nice as well, very clean & roomy. 

This semi-private nursing room is just off the main hall with comfy chairs and footstools. It lacks decoration though and coud use a livelier touch for a better nursing or pumping experience for mums.
