you know what i found really helpful for my babysitter...burp cloths....and they dont have to be like those big blanket things..my sister had little square white burp cloths and it also ended up being like a security blanket lol.....
also dont forget binkies....um..lol. pacifiers ...thats the real name ...pacifiers....

and tell your daughter...after feeding the baby formula....give some water in a bottle....or get little swabs to swab out the babys mouth....my mother made me drink some water and swab my mouth out everytime i drank formula and i still to this day dont have a cavitiy.....the dentist asked why my teeth were so strong and my mom told him what she used to do and he said it was a brilliant idea.....

dont forget socks ....and booties.....and what about that foam thing to keep the baby in place in the crib...its a big debate about letting the baby sleep on the stomach or back...but they have like foam protecters so the baby doesnt get their head stuck anyway....remember dont put to much stuff in the crib easier way for a baby to suffocate....

good luck...if i think of anything else ill let you know....!!!!!
love,
