Nipple shields & introducing the bottle

Mabillon

anyone have experience to share on when to introduce the bottle if we're still on the shield?

 we've weaned off supplementing (pumped bm thru syringe/tubing) this week!  however, our lac cons suggests we wait 'several weeks' before bringing out the bottle. buuut, i selfishly want to go to a wedding when dd will be 7 weeks and want to go without her (and drink more than one glass!)  

 what do you think?  can we try to introduce during week six without ruining breastfeeding?  what if we're not off the shield yet?
