I am not a doctor but have noticed my baby move more when hungry or after meals when relaxing. Or stressing out. Otherwise, when I am active - he is quite and not moving much.
My boyfriend does say he feels him move during night quite often when I sleep.
I wouldn't worry, you need to feel them move 6 times in a 2 hour period. I find in the morning when I wake up, after I eat and at night when I'm lying down she moves the most. Try to drink a glass of juice and see what happens. If your worried go to labour and delivery they told me to at any time I don't feel the baby move 6 times in 2 hours. Good luck :)
Wait a couple more weeks and you will feel plenty of movement as the baby grows and begin to run out of room to move lol
They say u only needs to pay aention from 28 weeks as bubs might just be facing inwards etc so u cant feel it. If u r concerned just go and get checked. Motherly instinct is good
My son first started kicking around 24 weeks but he didn't really do it often until around 26 weeks now it's non stop lol but I don't think there's anything to worry about
