Baby boy not showing any interest in rolling

I am and someone once said to me its boys just being lazy 😂 my little boy was like this put him on his tummy for tummy time and see if he rolls from front to back as that is so much easier :) x

My girl is the same she’s close to sitting for a few secs unsupported but rolling she just isn’t interested

My girl 5 months almost 6 on the 7th and she been trying to roll over but haven’t gotten it quite yet her arm be in the way as is she can’t pull it out lol and when it comes to sitting up she sits up a lil bit but start to lean forward until she falls over lol

My sons 5 months end of this month not even showed signs 😂
