Just start putting it together. Once he sees you struggling he will be forced to do it for you. Not even kidding, this works great.
Haha that is what I was thinking too. I would plop myself down on the floor with some music and start working on the crib. Husband sees pregnant lady working feverishly on said crib and guilt would ensue.
I love and respect my DH more than anything in the world, but I have been known to pull this a few times in our relationship ;o)
I agree with this too. We assembled our crib shortly after it arrived because we wanted to make sure everything was in order. As it turns out, some of the hardware was defective, and I managed to get the last set of hardware the store had in stock - otherwise we would have had to wait until January! Also, putting together the crib we got was definitely a 2-person job, so if you can, I would do it while you're still able to help out.
