Thanks everyone...some really good suggestions and it's good to know that this experience isn't unique to me and DS.

We do express - but not often - but have no issue switching between bottle and boob so I'm going to do it a bit more for the next few days (meaning once a day) to give me a break - DH is more than happy to do what he can to make it easier. In fact, right before logging on I expressed a bottle for this afternoon.

We have an ergo (with the heart to heart infant insert) but it's still in the box - I think we will bring it out this afternoon if/when DS gets fussy and at least I won't feel trapped on the couch for 5 hours.

Also have nipple shields that I haven't used and forgot about but that's a great suggestion to put them on to protect them from all the sucking.

Thanks again!
