Helper or IFC

Hi mummies, your advice please. I am currently having a helper. She look after my elderly mum. I have an infant and a 2yr old toddler. My toddler goes to a full day cc. As i will be returning to work after my ML, i am not sure to put my bb in ifc or ask the helper to look after. The helper has no experience in bb care, and i have been training her for the past 2 weeks, yet, she is not proactive and she is impatient and she got attitude problem. Happy do, not happy, don't do and she will talk back if she not happy. Her contract is ending in april next year and we have no intention to renew her either. If you were me, what would u do? Thxs.
