Re: Milk supply post 12 months
To be clear, are you nursing when you're with her and giving bottles while you are at work?
If so, it's perfectly okay to stop pumping altogether during the day. As long as your daughter still nurses 3-5 times per day you don't need to introduce any other milk (cow's milk or alternative) unless you just wish to. And of course you can continue to pump and send milk if that's your preference. But pump weaning at around one year old is common and it will not affect your milk supply when you are with her. Your supply is well-established by this time and will very quickly adjust to meet your child's needs, whatever they are.
And you didn't ask about it, but I'd ignore your ped's advice. There is absolutely no need to limit your child's breast milk intake now or at any other time, unless you are actively trying to wean.
