Just wanted to share my recommendation for the Barkantine Birth Centre - it's a great place to give birth. Really worth considering if you live within travelling distance of the Isle of Dogs. You don't need to be a Tower Hamlets resident.
This type of Midwife led birthing centre really is quite rare, and with all the cuts going on the phrase "use it or lose it" springs to mind.
Here is a bit more about my experiences there..
