Well normally i would advise you to ask your husband to look after her once he is at home.
I think there are some ahadith (hadiths) which show that our Messenger (peace be upon him) used to pray even if his grandsons where playing around or him but i couldn't find an english translation. Which i wanted to quote to show you that carrying a child won't break your prayer!
But at least i found a hadith which might be much better and clearer about this matter and help you:
Narrated Abu Qatada Al-Ansari:
Allah's Messenger (ﷺ) was praying and he was carrying Umama the daughters of Zainab, the daughter of Allah's Messenger (ﷺ) and she was the daughter of 'As bin Rabi'a bin `Abd Shams. When he prostrated, he put her down and when he stood, he carried her (on his neck).
[Sahih al-Bukhari. Al-Muwatta', Sunan abi Dawod]
So try to pray while carrying her and if your husband is home ask him whether he could help!
And Allah knows best!
