Lines from Macbeth: "I have given suck.."

[Tom]

Hi

Could you please help me understand what lady Macbeth is saying in the following lines?

"I have given suck, and know
How tender 'tis to love the babe that milks me."

Put in a less poetic way:

"Having breastfed, I have experienced a tender love for my suckling baby."

Doesn't Shakespeare express it beautifully, though?

I like the version I gave you less and less. How about this one?:

"Having breastfed, I know how tender the love for my suckling baby is."
