I can NEVER catch my son moving around in my belly on camera ! I swear he knows that I'm recording and he stops altogether. 😞 Like I just want to record this moment to keep forever . I know I'm just 30 weeks but hopefully he will allow me to record him as i continue to progress. It really makes me sad that I can't catch him lol
