Messenger of Allah ﷺ was praying and he was carrying Umama the daughters of Zainab, the daughter of Messenger of Allah ﷺ and she was the daughter of 'As bin Rabiʿa bin ʿAbd Shams. When he prostrated, he put her down and when he stood, he carried her (on his neck).  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُصَلِّي وَهْوَ حَامِلٌ أُمَامَةَ بِنْتَ زَيْنَبَ بِنْتِ رَسُولِ اللَّهِ ﷺ وَلأَبِي الْعَاصِ بْنِ رَبِيعَةَ بْنِ عَبْدِ شَمْسٍ فَإِذَا سَجَدَ وَضَعَهَا وَإِذَا قَامَ حَمَلَهَا  

I saw the Messenger of Allah ﷺ saying the prayer while he was carrying Umama, daughter of Zainab, daughter of the Messenger of Allah ﷺ. and Abu'l-'As b. al-Rabi'. When he stood up, he took her up and when he prostrated he put her down, Yahya said: Malik replied in the affirmative.

Yahya related to me from Malik from Amir ibn Abdullah ibn az- Zubayr from Amr ibn Sulaym az-Zuraqi from Abu Qutada al-Ansari that the Messenger of Allah ﷺ used to pray carrying Umama, who was the daughter of his daughter Zaynab by Abu'l As ibn Rabia ibn Abd Shams. When he prostrated, he put her down, and when he got up he carried her.

[Machine] I saw the Messenger of Allah ﷺ while he was praying carrying Ummamah bint Abi Al-As or Ummaymah bint Zainab, who was the daughter of Zainab. He carries her when he stands and puts her down when he bows until he finishes.  

رَأَيْتُ رَسُولَ اللهِ ﷺ وَهُوَ يُصَلِّي يَحْمِلُ أُمَامَةَ أَوْ أُمَيْمَةَ بِنْتَ أَبِي الْعَاصِ وَهِيَ بِنْتُ زَيْنَبَ يَحْمِلُهَا إِذَاقَامَ وَيَضَعُهَا إِذَا رَكَعَ حَتَّى فَرَغَ
