Trying to wean, but wont take formula...?

my daughter is 6.5 months.. not planning to completely wean her til at least 9 months.. I'm expecting my #2 and since she is addicted to feeding, i'm trying to start a little early on weaning. i'm sure it'll take her 2 months to fully wean.. so today i tried to give her formula and she wouldn't take it, she's been like that since the day she was born.. she hates bottles, she only bites them. i tried feeding her with the sippy cup, but she'll have a taste then throw the cup. she hates her pacifiers and anything artificial. and she wakes at least 2 times at night to feed( i feed her cereal before bedtime), that's the only way she falls back to sleep. i've been trying the cry out method, but at 2 am my husband just wants to sleep!!! not so easy.. so i'm trying to get her at least to sleep through the night for now. and try to get her used to the bottle... HELP!!!! i'm just afraid when my belly is huge i wont be able to feed cuz she's heavy enough to carry.
