COVID 19 - How to take care of baby

Hi mummies I have COVID 19 and is looking after my 10 month old at home when she is not in IFC. I am wearing a mask all the time and practising social distancing from the baby. May I know when is the 'safe period' to remove my mask if the test kit tested negative. I understand that sometimes even if the test kit is negative and we feel we have "recovered", the virus may still be contagious inside our body. Can anyone advise me when to remove my mask totally and any tips to take care of baby if contracted COVID 19? Thanks so much ! #adviceappreciated #firsttimemom
