BABY MOVEMENT WHEN OVERWEIGHT

Im 18 weeks pregnant with a baby girl🌸, a first time mom and im really overweight, my bmi is 29. I get the “muscle twitches, taps and sometimes fluttering movements” occasionally but im not yet at the full kick stage, the taps are sooo random i cant wait to be really sure its not just gas or muscle spasms. I have a posterior placenta and at my 17wks+6days ultrasound, my babygirl had turned head down.

When should i expect my husband to be able to feel the baby move?
