My 5 month old DS will only feed for a few minutes each time I offer him the breast in the day, between 1 min and 10 mins per feed, usually around 3 minutes.
Surely this is not enough! I have tried making him wait three and a half hours between feeds - he still only has a short feed, the incorrigible little beauty 
So, I continue to offer him a feed quite often, just to try to ensure that he gets enough calories in the day (which he probably doesn't - he makes up for it at night though, wakes 4 or 5 times).
I feel that this must be reducing my daytime supply, which won't help him sleep through any time soon.....Ultimately he needs to be getting his milk in the day.
Perhaps he's just a REALLY efficient feeder?!
I am considering giving him a morning bottle of formula, to see if it helps him, but am aware that will affect my supply for sure... 
Has anyone experienced this or got any advice?
TIA
