Schedule Appointment For:
A: Yes, very normal! Baby hiccups happen as they practice breathing movements. You might feel rhythmic, jerky movements that last several minutes. This is actually a good sign - means respiratory system is developing. They're not uncomfortable for baby.
A: Left side is considered best because it improves blood flow to baby and helps your kidneys work better. However, either side is fine - the key is to avoid sleeping flat on your back. Don't stress if you wake up on your back - just roll to your side.
A: Third trimester (starts next week at 28 weeks) brings: more frequent prenatal visits, possibly more tiredness, bigger belly, Braxton Hicks contractions, preparation for birth, nesting instinct. Baby will be gaining weight rapidly. It's the final stretch!
A: By 27 weeks, typical weight gain is 7-10 kg for women who started at normal weight. However, healthy weight gain varies based on starting weight. More important is steady gain and nutritious diet. Discuss with your doctor about what's right for you.
A: You can start noting movement patterns now. By 28 weeks, many doctors recommend formal kick counting. After a meal, lie down and count movements - aim for 10 movements in 2 hours. What matters most is knowing YOUR baby's normal pattern and noticing any changes.
