We are waiting til after our gender revel party for clothes and then after our baby showers. But my mom had given me her bassinet and she found a bathtub and some clothes for me. So it just depends on you.
It's abit harder for us because we are not finding out the sex so everythin has to be neutral. My mom has brought us a bat set but is keeping it at hers we haven't brought any big stuff as of yet just bibs and baby grows n blankets really and that's all people have given us, the bigger stuff will probably be after 20 weeks I think
We waited until after my 22 week ultrasound, it just seemed like a good amount of time to wait. Then we went right out and picked out the crib, bassinett, pack n play, changing table, car seat and stroller :) we also started our baby registry that day.
