Pleasing eachother husband and wife without having intercourse.

Assalamoalaykum W W. Alhamdulillah Allah sw has granted us 1 beautiful intelligent daughter and we are expecting inshallah another in the very near future. We have had several miscariages in the past and have been told not to have intercourse.we are scared again that we might lose the pregnancy if we have intercourse.9 months is a long time. Is it permisible islamically for us to please each other using hands/fingers please advise.jazakallah.
