Tahniah, mama! Alhamdulillah, what a blessing, 12 weeks is such a milestone, dah boleh relax sikit kan selepas first trimester ni. A few of my mum friends yang ada kakak-adik story cakap the key thing adalah involve the kakak in the journey, baca books together pasal baby coming, let her feel the baby kick nanti, it makes such a difference in how she accepts the new sibling. Make sure juga the first daughter feels special and secure la, sebab change is big for her too. Congratulations again, mama, you're gonna rock this!
