I'm using philips Avent classic bottle 0 + size still baby leaks from sides if I go for pegion which nipple flow i need to choose

A. Ma’am you have to check with the size of the nipples as this way I cannot confirm honestly Philip is one of the best brands and better than pigeon also but if you’re facing a problem then with pigeon also you should use 0-3 only that would be a better size
