Week 29: I'm spleen-tastic!

If you’ve been feeling weird little fluttering butterflies in your belly, it’s not just your run-of-the-mill pre-birth performance anxiety.

Actually, it's your amazing baby with a case of the hiccups: a fairly common occurrence at this point, due to them practicing breathing for their big birthday.

In addition to getting a round of butterfly-like hiccups, your little swimmer has arduously managed to accumulate enough baby fat to account for nearly 3.5% of their overall body weight.

Yeah, compared to we lardy adults, it’s not very impressive, but considering they used to have NO fat, it’s certainly a healthy (and body-warming) accomplishment in its way.

Another fantastic life-critical accomplishment: your baby's spleen is now in charge of hematopoiesis — the 10 dollar name for the process involved in building up certain important blood components.
