2059 — ʿAbd al-Salām ibn Muṭahhar narrated to us that Sulaymān ibn al-Mughīrah narrated to them, from Abū Mūsā, from his father, from a son of ʿAbd Allāh ibn Masʿūd, from Ibn Masʿūd, who said: "There is no [valid] suckling except that which strengthens the bone and grows the flesh." Abū Mūsā said: "Do not ask us while this scholar is among you."(1)

2060 — Muḥammad ibn Sulaymān al-Anbārī narrated to us, Wakīʿ narrated to us, from Sulaymān ibn al-Mughīrah, from Abū Mūsā al-Hilālī, from his father, from Ibn Masʿūd, from the Prophet ﷺ, with its meaning, and he said: "which sets the bone."(2)

=============================================
Al-Khaṭṭābī said: Its meaning is that the suckling by which [marital] prohibition is established is that which occurs in infancy, when the child is nourished by milk and it satisfies his hunger. As for that which occurs after this, in a state where milk no longer satisfies his hunger and he is not filled except by bread, meat, and what is like them of solid food, then there is no prohibition in it.

(1) The ḥadīth is authentic by virtue of its witnesses, but this chain is weak due to the unknown status of Abū Mūsā al-Hilālī and his father.
It was also narrated by al-Dāraquṭnī in al-Sunan 4/173, and al-Bayhaqī in al-Sunan 7/460-461, via the path of Sulaymān ibn al-Mughīrah, with this chain. Al-Dāraquṭnī's narration is raised (marfūʿ).
See what follows.
It has a witness from the ḥadīth of Umm Salamah, recorded by al-Tirmidhī (1152), al-Nasāʾī in al-Kubrā (5441), and Ibn Ḥibbān (4224), with the wording: "Nothing is made forbidden by suckling except that which splits the intestines while at the breast, and that which is before weaning." Al-Tirmidhī said: This ḥadīth is ḥasan ṣaḥīḥ, and the practice according to most scholars among the Companions of the Prophet ﷺ and others is that suckling does not make [marriage] forbidden except what is within the first two years, and what occurs after the completion of two years does not forbid anything.
Another [witness] from the ḥadīth of ʿAbd Allāh ibn al-Zubayr, recorded by Ibn Mājah (1946).
And a third from the ḥadīth of Abū Hurayrah, recorded by al-Bazzār (1444 - Kashf al-Astār), and al-Bayhaqī 7/455.

(2) The ḥadīth is authentic by virtue of its witnesses, but this chain is weak due to the disconnection between the father of Abū Mūsā al-Hilālī and ʿAbd Allāh ibn Masʿūd, and due to the unknown status of Abū Mūsā al-Hilālī and his father. The author has connected it before this. =
