Mis_tree i just wish to warn you to be very carefull whist you don't have the court orders. Your ex can simply not return your son when he takes him for visitations and hold him till the court say's other wise. He is 50% his and 50% yours in the eye's of the law. I have been through this, i don't wish to scare you only inform you. It's great you give him time with your son that will go in your favour but be sure he is not likely to keep him. Also have it noted that you wish for your son not to be given a bottle of any sort babies get nipple taet confusion and refuse the breast as it is easier for them to get the milk out of the bottle. This is something my ex has threatened me with so he will get our newborn sooner for longer periods. If he does not manage to get the custody from birth. Which he won't (fingers and toes crossed ) I suggest that you only allow supervised visits till you do have the court oders and they are signed by the magistrate.
Don't worry about DOCS at all if you sought help for your problems then that shows you have done everything you can in the best interest of your child lots of mothers go throught PND and they don't loose there children. As for what he said or says to you it is so important to write it all down in a diary even if you don't remember the dates the courts will look at all of that.
As for him taking things from you and money from your accout that is such a low act mine did the same but again write it down. Everything thing these days is for THE BEST INTEREST OF THE CHILD and he is oviously not thinking of his son, only himself and how to hurt you. If you have it all written down the courts will use this against him.
