Incontinence after radical prostatectomy

Hi all, 

Husband is now 7 weeks post radical prostatectomy. Recovery seems to be going well. They were able to spare one side of nerves and already able to maintain an erection hard enough for penetration which we are extremely thankful for, however the incontinence is getting him down. Is he expecting too much too soon? Pretty much dry through the night and first thing in the morning, but leaks quite a bit when moving around. He is doing his kegel exercises every day. Is there anything else he can do to help or does this recovery sound quite normal and he just has to be a bit patient? 
thanks for reading.
