As some others have said stop dog, maybe you should try to remember your mother's care from a non biased person. It's highly unusual for a baby to reject the mother unless the mother has rejected it first. According to the attachment theory infants are highly sensitive and their only way of communicating is through non verbal facial expressions and through the care they receive: touch, hugs, love. They morrow what they receive.
I know your mum says you rejected her but perhaps you were so attuned to her that you picked up some resistance on her part. A lot of rejection comes from a parents misattunmentattunment. Can you imagine a baby who has just been fed and is drowsy and a mother interprets that as bored and starts to wave a rattle in its face thinking he wants to play..The baby will become irritated and scream and reject when she then wants to hug him. So there cam be lots of misattunmentattunment s.

Have any of you seen the film " We need to talk about Kevin"?
