He will eventually give up these nursings (daytime, etc) however it depends on how long you're wanting to let him go!! (I let mine wean themselves and one went 3.5 yrs, one went a little over a year and one is still going, 4 months) so there ya go!!
Check out www.kellymom.com. BEST breastfeeding site I've found so far!
Good luck!
