Yes I think it’s linked to their development at 3-4 months old, as they get more aware of their surroundings and get distracted. I’m only managing to get him to do a decent feed when he’s drowsy at the moment. Not sure about the throwing up though, I would maybe ask your gp or health visitor about that if it is a new thing.
I tried a breastfeeding cover and it stops them being as distracted, they’re breathable to they’re okay under there.. it’s helped me get my boy to feed for longer with less distraction, it eats into his wake window more so I have less time for developmental things before he goes to sleep again but he has to be fed so I’m still finding the balance of doing both
Yep 🤷🏼♀️ . Can’t offer any advice but having the same issue.
