Hopefully Melonscoffer will never find herself in a situation where she is ground down so much by a bully that she doubts herself and is taken in by words spoken with utter confidence.
And no, it's not theft, fawkesAgain2. She will be taking the baby's belongings and equipment that the baby will need. Not the fridge.

A few people have mentioned woman's aid, will their advice be legally bound if I was to say that they advised me?
Please, please @BabyPufflingMumma do not engage with this abusive man on the topic of the cot or the baby's toys and little things. Do not quote anyone, do not engage in arguments, or discussions on who is right here, or who has the law on their side. You do. Your H is trying to confuse you and intimidate you.
Women's Aid do not give legal opinions. They are there to offer support, advice on practical matters, and shelter if needed. They will be a fantastic resource for you as you take steps to leave your abuser. Please call 0808 2000 247. If you get a machine, leave a message telling when you are available for a call back. They may be able to refer you to a solicitor familiar with the dynamics of domestic abuse who will assure you that of course you can take the baby's belongings, and go to bat for you on finalising the divorce, getting back your share of house payments, child support, etc.
Quietly arrange your new home and then dismantle the cot, pack the baby's belongings, and leave. If possible, have a male relative or actually anyone reliable there with you for support and help with a screwdriver when moving day comes. You need to line this up as a matter of urgency. Try not to do moving day all on your own. Do you have any colleagues who might be able to help? Friends? Family? They will need to be able to play your cards close to their chests.
For now, concentrate on getting documents together - baby's health records, birth cert, your own documentation, any photos you want to copy, financial documents relating to the mortgage, your bank accounts, your contribution to the household, as well as any info on pensions your H may be contributing to.
You can also pack out of season clothing and footwear of yours and if there is a friend or relative willing to help, have them take these and store them for you.
Make sure you log off MN when you are finished with a session.
