Advice please on cots

Hi fellow mummies I’m looking for some advice, my daughter is almost 3 weeks old on Wednesday and obviously so far we’ve been keeping her downstairs with us in her Moses basket during the day when she’s snoozing. But lately my two other kids are starting to wake her when they get too loud 🙄 so was thinking to put her upstairs in her cot in her own room when she’s sleeping during the day as it’s more calm and quiet up there. Obviously I’ll put the video monitor on up there so I can see her. But I’m just wondering is she too small to sleep in cot yet? Or should I just keep her in her Moses basket up in our room in the day with monitor on? She sleeps in our room now in her basket at night and I’ll keep her in our room for a while more but just for naps can she go in her cot? Will it help get her used to it ready for when she goes in to her own room at night 🤷🏻‍♀️ advice please ☺️
