Berat baby twin 28w?

Ahhh don't worry lah, at 28 weeks those weights sound normal for twins actually, babies grow at different rates and positioning boleh change anytime, so the fact that one is still transverse (melintang) is quite common at this stage pa. A few of us mum friends had twins yang siap melintang sampai 32-34 weeks baru they flipped, so there's still time! But definitely check with your doctor at your next scan or checkup, they can monitor the positioning and make sure everything's progressing well for both babies, especially since you're carrying quite petite. You're doing great lah at 22 with your second baby, just relax and trust the process, these things usually sort themselves out
