Help! 😩

We’ve been practicing more with the bottle since I go back to work soon, and now baby is acting frustrated and doesn’t want to latch at the breast 😭😭 he’s had a bottle since 2-3 weeks old but usually only 1 a day/every other day. He takes a pacifier fine, but now that we’ve been doing at least 1-2 bottles a day this week to practice getting used to bottles while I work, and now he isn’t wanting to breastfeed... we are using slow flow bottle nipples and pace feeding. Any advice on how to help this? I do not want our breastfeeding journey to end!! 😢
