Sayang, anak besar seizure when crying at that age mmg boleh happen, but please get her checked by paediatrician first to make sure semuanya OK.
Honestly, kalau mama burnt out, that's the real issue here, anak pick up on our stress, jadi dia tension lagi. Minta hubby or family tolong ambil alih few hours per week so you can breathe. No shame in saying "I need a break", that's not neglect, that's self-care. Kalau lama jugak, jangan hesitate nak talk to counselor or GP about how you're feeling. You can't pour from empty cup, babe. Sending you strength
