Cloth diapers patterns or other patterns?

Im kind of wondering if I should wait till my baby is born to take measurements, but feel like this is the time thats free that I can sew without the stressfull baby crying and stuff. I have LOTS of fabric and clothes that dont fit me that I can use for fabric, and am wondering if there is somewhere, preferably cheap to get ahold of patterns for things that have to do with babys like those backpack or sling things they fit into or cloth diapers, diaper covers(still dont know if Im using disposables), booties, dresses or clothing, hats, anything I can prepare myself with that a baby might need or even want like soft toys, or pillows(?). the only problem is I dont know what size my baby will be or if its a boy or a girl. Ive looked at all the crafts stores that sell sewing patterns and am not finding anything except for like $18 which is like way more expensive than buying the clothes at thrift stores that's for sure. Anyone got any tips?
