Boston terrier puppy agression

Question
Hello,
I have a 4 month old boston terrier puppy that bites (actually breaks the skin), is he is disturbed while sleeping.  He also has bitten my 5 year old daugther, if she picks him up.  I wanted a child friendly dog-especially since we have a baby on the way.  I am concerned that I will have a child in my house who will come upon this puppy and will be hurt very bad.  Can I work on this agression, or do I need to give this dog to a rescue group. Basically, can I get his agression under control, and if so, how do I go about doing that?

Thank you so much for your help.

the best way is with a trainer,as they can show you you how to correct these unwanted problems-and this is a serious issue and will be easier to fix now,rather then later

Trainers can fix problems like this esp if the dog is still very young,as as this one
