My little one is going to have to go to daycare after 12wks, so will have to use bottles.  I'm really not sure what or how many I will need!  Any ideas?  We got the AVENT Natural glass gift set - two 8oz bottles, three 4oz bottles, with 3 newborn and 2 slow flow nipples - they are supposed to be petaled to mimic breast feeding.  It was $60 for the set!  I had no idea there were so many bottle choices, nipple choices, nipple flow rates, etc!  I thought glass would be easier to keep clean.  Seems like only three 4oz bottles would mean I would have to clean them every night - if that's even enough? Anyone have any insight?
