Would it be weird to...

So I’m currently pregnant with my second child and I plan to EBF for at least the first three months then use bottles as well. I breast fed my first born for four months then because I didn’t have a ton of support and issues with over producing, I gave up.

My question is, would it be weird to give my four year old a small amount of breast milk daily once my daughter arrives?

breast milk is just so healthy and I would probably mix it in with his breakfast shake.

Opinions?
