I can't help you on the BFing part of it, I never did with my second child, but I have done with my #4 child - so that was with a 4 year old, 2.5 year old and a nearly 16 month old - so it can be done!

I'm not sure I can help with any tips, I think you sort of learn what works for your toddler as you go along, what worked for mine may not work for you - I know I use the tv though! Books are good too. Plus you can sit on the floor and feed the baby, so can play with blocks with them with your spare hand if you really have to
