I put mine together all by myself when Hubby was at work at 37 weeks.

I guess it could also depend on what crib you have. I have the sleigh crib, with no drop down rails. It was really easy to put together. However, I did have hubby help me get it out of the box, because the box was VERY heavy.

I put mine together myself along with the stroller the glider everything because my hubby has been deployed this whole pregnancy so I had no other option and Im not the type to just sit back and relax I have rearranged furniture been cleaning my house left and right and my pregnancy has been smooth sailing just if you feel like your getting over worked chill for a minute or two
