EBF weaning

Hi everyone, FTM my baby is EBF and doesn’t even take a bottle. He’s 9 months now and I’m starting to think about what we’ll do when he hits 1year, I’ll probably still BF for as long as I can but can feel I may be running out of steam. I would prefer not ever to give my baby cow’s milk.

So, if that’s the case what is the alternative? How long do they need to drink milk for?
