Introducing the bottle

Abby

Hey all first time mom here. I am currently breastfeeding my 1 month old son and my question is when did everyone introduce the bottle? I don't go back to work for awhile but I am going to a wedding in a few weeks and my mom will be watching him so he will need to have a bottle then...also once you introduced the bottle how did u go about you little one feeding from bottle and breast?? I don't want to only do bottle..
