Unconnected

Hi mummies! My 2 yo toddlers seems like be unconnected with me, always rejecting me, no idea why. I do have an helper but I work from home everyday so I still her main caregiver, play with her, shower for her etc. but she always ask for my helper or my mum if shes here for visiting. It’s so bad that she never even find me or look for me. Any toddler like this too? I feel sad and unwanted by my child lol
