I feel like I'm constantly saying no to my 3 yr old daughter. No, don't do this....Don't do that...put that down please. I just feel like I'm always negative with her! I praise her as well, but I'd like to try to stop her behavior in some other way. I can tell she is getting frustrated with me stopping her from doing things all the time and I think it is probably why she has stopped listening to me. Any tips or books I could read?
