During this CB period, me and my hub wfh. Meaning that we could spent more time at hm w my LO. All along she is taking care by my helper ard 3 mths until now.But this one week my LO refuse for her carry and cry very badly. When I carry her, she stop crying and smile at me. Idk what’s wrong with my LO. Any mummies encountered this before? My helper has issue or my LO?
