just be patient. the baby will let u know when he/she is ready for daddy to feel. lol
it all depends on ur build. with my first I really started feeling movements around 18 weeks. which is the same with this baby too. but with my first I was alot smaller then I am with this one. so my SO was able to feel the baby on the outside around 20 weeks. I think me and him will be able to feel the baby on the outside later in the pregnancy this time since I'm bigger.
these timelines all seem super early! I'm 28 weeks and feel movement and stomach "hiccuping" but no arms or legs yet
I have felt her for weeks. EVERYTIME he would put his hand on my belly she would get quiet. Now it's like she's hijacked me and moves all the time. He felt her for the first time on the 23rd :) I was almost done with week 23.
