Sounds to me like your male is trying to show dominance and tell the little female he is king of the castle. It is a normal behaviour. It is basically a pecking order and they have to work it out between them. Do not step in everytime she makes a sound. Unless it gets rough then just let them work it out for themselves. If it does get rough then separate them and put one in one room alone and the other in another room alone with closed doors. Kinda like a time out.

They are both young so once they work out the ranking in the household they should be best buddies. This should also happen rather quickly. Please keep us updated on their progress and do post some pics of the babies. What are their names? And BTW welcome to pet talk.
