At what age do you have to leave a baby with the father unsupervised (bearing in mind he see's her every 2-3 weeks for about 2 hours, cancels about 3-4 visits in between each visit, and doesn't ask about her or reply in between.) he also is completely uncaring and unappropiate with her to the extent i dont feel she'd be safe or happy with him. He seems to be more interested in controlling me than being her dad but i'm worried about how he'd treat her to get at me. when do you legally have to leave a baby ? She's exclusively breast fed still at the moment so its not an issue yet but want some idea of when to be prepared as its making me really stressed out all the time at the moment
