Why must i always be the bad guy....

This is my second pregnancy. And just like most women throughout my first and first portion of my second I have craved my mother to be there, but both times she has either had last minute things or I feel like I can't or shouldn't even tell her when my appointments are... The names I pick for my children I get told are stupid, and girly ( I have two sons). Like why can't she just be supportive...the only reason my child and soon to be children still see her and that side of my family is because I don't want them to regret me one day for not letting them get to know that side... But it is causing me so much stress which I know is not good for the baby. It sucks because of course when you pregnant you want your mother involved I thank the Lord for my mother in law and my awesome relationship with her.
