My DP's exP won't allow his 14 month old DS stay with him overnight because she says he's not ready to. She allows their 3 year old DD, but she refuses to (I think because she's being separated from her mummy and her little brother).
The little boy is still being breastfed, which I understand complicates things.
How can we support and prepare the ex to allow my DP to have both children overnight?
