When we went baby classes she would often feed during them, which a lot of other mams done. You can try to feed an hour before you go out and just have a spare bottle in your bag just incase x
I usually give her a feed just before we leave, I get up a bit earlier etc if it’s a morning class and then I feed her again when we get back if necessary. My girl feeds every 3 hours but is pretty patient though
Just change or feed in class
Our baby sensory class gives you 20 mins to change and feed if needed, it's completely normal at baby classes or events to expect to feed 😊i do try get a feed and nap in before I go to a class though as makes my LO nice and happy and alert for the class but don't worry if you have to feed! They babies and will not conform 🤣🤣
