Nabi (sallallahu ‘alayhi wa sallam)’s Grand Daughter: Umamah bint Zaynab

Not much is known about this grand daughter of Rasulullah (sallallahu ‘alayhi wa sallam). I came across this narration, and would like to know the source and if they are authentic?

Abu Qatadah reports that Rasulullah (sallallahu ‘alayhi wa sallam) was offering his salah and Umamah bint Zaynab was on his neck [shoulder]. When he (sallallahu ‘alayhi wa sallam) performed ruku’, he (sallallahu ‘alayhi wa sallam) put her down and when he (sallallahu ‘alayhi wa sallam) got up from his sajdah, he (sallallahu ‘alayhi wa sallam) would place her back on his neck.
