Breast to bottle

Brittany

Ftm here. I go back to work in a couple of weeks and ive started transitioning her from the breast to bottle and it seems like shes always wanting to comfort nurse after i have fed her from the bottle and today she has only slept for 20 min twice. It might be because shes gasy but not sure. Shes asleep finally now im hoping she takes a couple of hr nap. Just needing any advice if it gets easier or if i should just do a bottle to two bottles a day for a week and then amp it up next week just not sure how to make this easier on her and me. I have also made sure i got the size 0 nipples for avent bottles and i burp her between every ounce. Any advice is appreciated!
