Oh dear, you are doing so well already sebab siang hari dah berjaya, so please don't be too hard on yourself, malam memang the hardest part for toddlers this age because nursing is so tied to their sleep comfort, bukan sekadar lapar. Maybe you could try having your husband or someone else do the bedtime routine for a while so baby doesn't associate that time with you being there, sometimes a little distance at night helps break the habit more gently than anything else. Since your body is feeling so exhausted and sakit, and you are only 8 weeks pregnant, I think it would really be worth sharing all of this with your doctor or gynae so they can advise you properly on whether it is safe to continue even partially, and also give you some peace of mind. You are carrying so much right now as a working mom and an ibu mengandung, please be gentle with yourself, you are truly doing your best.
