hi my DS is only 11 wks but we do the same thing every night and he is great at getting off to sleep... at the moment LOL!!!!
we shower him (he likes that more than the bath) - very occasionally bath him
give him a quick massage (he is only starting to relax into it now... so it is getting a bitlonger)
i feed him one side in nappy
then put on his pjs and feed other side
little bit of rocking if he likes it
wrap and cot

this worked even all this week when we moved him from basinette to cot... and he is sleeping well.
i know you dont want to bathe her daily but it works for us.. you coud try adding masssage.

i also have a baby sleep cd playing from when the 1st feed starts.

good luck!
