I don't entirely agree with divorcelawyer on this occasion. Your D was very young for the sort of contact pattern you had. The organisation that advises courts on child related matters suggest that very young children stay with one parent and the other parent has contact little and often. They also say for developmental reasons backed by research that children under 3 can find overnights difficult and I think you might have a situation that your daughter is overwhelmed and mum interprets this as how awful you must be for the child to behave in this manner and contact is not in the child's interest whilst you interpret the child's behaviour as evidence that she is being turned against you.
A lot of patience and understanding is required to keep contact going because it helps children, particularly in these circumstances, to avoid the longer term attachment problems. When your D is secure in her attachments she will be more confident and happy to come to you.
I would suggest the key is effective communication with your ex-wfe and in the first instance alternative forms of mediation or formal negotiation are always worth a shot. Family counselling or even family therapy could be a forward. (I have no vested interest BTW) If matters can't be sorted you will need to apply to court and the fact you have tried alternative dispute resolution is evidence that you are trying to be reasonable.
