I am not sure if you are still looking but I would recommend a friend of mine called Corina Bankhead:
http://corinabankhead.com/
She has photographed my two year old since she was born and we absolutely loved the pics. She does families as well and has quite reasonable packages on offer.
I am also an experienced Hair & Make up artist and occasionally work with Corina but also lots of other photographers. Both Corina and I are based in Southfields. Please give us/me a call if you are interested.
