How old is your little man?

Not being able to pump a lot is not necessarily an indication that your milk is drying up. I was never able to pump a lot (I could never get the hang of it!) but I had a plentiful supply for both DS1 and DS2.

I don't have a lot of advice to offer with regard to your bub going to your parents for the night, DS2 has just turned two and I've never spent a night away from him, so I have no idea!
