Kicks may now be powerful enough to wake you up, and you may be noticing clear patterns in your baby's daily activity. Your baby continues making important progress in brain development, lung development, and sensory awareness, and the third trimester is just around the corner.

Frequently asked questions

Can my baby open their eyes now?

Possibly. Around this stage, many babies begin opening their eyelids for the first time and can detect light and darkness.

What do baby hiccups feel like?

They often feel like small rhythmic taps or repetitive movements in the same area, lasting several minutes at a time.

Are stronger Braxton Hicks contractions normal?
