I started feeling my baby girl around 18 weeks and my husband could feel her around 21 weeks. It's pretty cool to see/feel! My husband was excited because he could finally connect with her once he knew he could feel her.
My hubby felt for the first time around 20 weeks.
I felt my baby fluttering around at 16 weeks as i have had 3 previous pregnancys and a sensitive uterus. My bestfriend felt her kick at 19w&5 days on the outside of my belly. I am now 29w&5 days and yoi can litterally see her rolling and kicking like crazy! It wouldnt suprise me if your bf felt kicking on the outside now. As pretty soon it'll become stronger and u will see it on the outside!
Hubby felt our little one for the first time around 24 weeks
My bf felt are daughter kick for the first time at 22 weeks its different for everyone. So he might have :)
