Get a sippy cup of water that doesn't leak and put it in reach in his bed...then when he wakes you could offer that first. If he's hungry you'll know because he won't settle without a boob!

I would try maybe next weekend or when your dh is home to help/let you sleep in.

If it's a disaster you can keep feeding as you are and try again in a month...his level of understanding is growing exponentially and soon he will understand that 'boobies are asleep'.

Try searching for some threads on night weaning...I'm sure there have been some.

Good luck!
