There are a bit gentler ways to wean but if you have been going for a few days without and he is starting to forget then I recommend just keep going with it. You can go a bit slower with the next baby (lol)
You might find your breasts full of milk - mine went rock hard - for 5 days or so, but once your body realizes there is no one drinking it it will the milk production will go down.
I used crushed cabbage leaves in my bra to cool. I felt it helped for the pain. And there is a supplement that you can get at health stores to diminish milk supply, I will look it up and email you later.
I weaned all my children around 16 months. more or less within 2 weeks, 3 with a lot of discomfort to me - the last one effortlessly. We also do not get pregnant while I am nursing. All my children went through it fine.
Weaning is one of mothers first lessons (with birth being the very first) how to start letting go of our children. Having to let go of something always hurts deep in our heart. But as you know, this is just the first of many and you might as well throw yourself into it and work through it. You will find all the little "letting go moments", and how they all give you a little pinch in your heart... the first time he walks on his very own, the first time he stays overnite with grandma, the first time he chooses to tell a secret to a friend instead of you... the first time he leaves for elementary school, college, moves out...
and every time he does you will see that because you are supportive and able to let him go, he will be fine and confident and excited about the next step.
he is a big boy now :) good for you!!!
Live it deeply - feel the pain in your body as well as your soul, hold him close, snuggle him for naps and in between play time. Just give him love in other ways, tell him that you love him so - He is fine. When he asks about it tell him: you drank it all, it is all gone. :) He knows. He already moved on. You would just confuse him by giving it back. And as for: you don't be sad about not being able to breastfeed, you are going to have another baby! you can do it all again!
:)
congratulations to you for being a wonderful mother!
