Wa'alaikumassalam warahmatullahi wabarakatuh! Aih mak, hamil dengan 2 orang anak memang penat sangat, kesian jugak tu badan nak support semua tu, especially kalau kids yang energetic. A few of my mum friends yang pregnant with young kids, they say the aches get better bila dapat rest sikit sikit, even 10 minutes lying down with legs up membantu, and make sure makan protein + calcium enough sebab badan really stretched. Don't push yourself too hard, and jangan segan minta help dari partner or family because you really deserve it during this time. Semoga sehat selalu dan delivery nanti lancar!
