So. My little one is having a really hard time when it's about burping. He is moving his hand toes and his  head gos here and there  like he is breakdancing - really difficult to control! and all that when i hold him in a position on my shoulder trying to help. Any tips on helping him? He is even grying sometimes. 😞Â
