Baby carrier... Life saver?

Colleen • FTM living with hubs and lil Declan Patrick in sunny Florida...
I have a baby carrier and I'm just waiting for the separate infant insert to arrive tomorrow for my one month old. I'm ecstatic thinking of all the things I might be able to get done around the house while perhaps simultaneously rocking my LO to sleep. Is this a realistic expectation or have I set my hopes too high? Do you have one and use it a lot and love it? Thanks!
