My yorkie after her babies was fine with myself and anyone touching her or her babies. If they were picked up she'd just get excited and very alert to what you were doing with them. She never barked or got angry at anyone.
However I have other dogs and she was very aggressive with them all. If they came into the room where she had her whelping box she would immediately jump out and attack them. Needless to say no dogs could enter my room. She was ok with any humans from day one.
Good luck and I hope things work out for you. Try offering her a favorite treat and speaking to her nicely and maybe she will calm down.
