Just thought i'd say my friend had a boy with a 38cm head and it was 40cm on day 3 - it had moulded down to 38cm in the birth canal so he could get out. She had a long pushing stage (2 hours for a fourth bub) but he made it out ok...just in case you ever want to VBAC in the future.

I'm so glad your birth went well, i know you were worried about it. Many congrats on your lovely bouncing boy too!
