Supermaning when feeding

[Meepmoop]

My DS is 14weeks old and the last few days when I tried to feed him on my right side he keeps 'supermaning' head up, back arched, legs up. It's becoming a battle to get him to latch on. He literally rolls away.

Is this a normal age thing or can I do anything to stop him. He's always been better at feeding on my other side

Thank you

My 9 months old does this, he does it when something distracts him, I used to feed in my bed room where it was quiet and dark but now I just roll with it 😂 sorry !
