Peace be on all.
1=At two places Qurans says about two years suck giving:
[2:234]
And mothers shall give suck to their children for two whole years; this is for (man) who desires to complete the suckling. And the man to whom the child belongs shall be responsible for their (the mothers’) food and clothing according to usage. No soul is burdened beyond its capacity. The mother shall not make
the father suffer on account of her child, nor shall he to whom the child belongs make
the mother suffer on account of his child, and the same is incumbent on the heir. If they both decide upon weaning
the child by mutual consent and consultation, there is no blame on them. And if you desire to engage a wetnurse for your children, there shall be no blame on you, provided you pay what you have agreed to pay, in a fair manner. And fear Allah and know that Allah sees what you do.
[31:15] And We have enjoined on man concerning his parents —
his mother bears him in weakness upon weakness, and his weaning takes two years — ‘Give thanks to Me and to thy parents. Unto Me is the
final return.
2=At third place, a duration of 30 month is mentioned as:
[46:16] And We have enjoined on man to be good to his parents. His mother bears him with pain, and brings him forth with pain. And the bearing of him and his weaning takes thirty months,till, when he attains his full maturity and reaches the age of forty years, he says, ‘My Lord, grant me the power that I may be grateful for Thy favour which Thou hast bestowed upon me and upon my parents, and that I may do such good works as may please Thee. And make my seed righteous for me. I do turn to Thee; and, truly, I am of those who submit to Thee.’
Possibilities:
Two year milk feeding is a variable limit which could be less or more:
"Long-term breastfeeding (extended breastfeeding) is when you continue to breastfeed your baby
beyond his first year.
If you decide that it's right for you and your baby, you're in good company with other mums around the world.
In many societies, the age of weaning from the breast ranges from two years to four years."

=====
30 month:
a- about 9 month + 21 month milk feeding
b- After 3 month, next 6 month are special
http://www.motherandbaby.co.uk/preg...ice/time-for-your-12-week-scan-what-to-expect
so count that:
6 + 24 month milk feeding = 30 month
There can be other possibilities
There is really no case here mahasn.
