some parents it doesnt matter if your 30 years old and a millionare, "your to young to be having a baby" lol im glad my mom and dad aren't control freaks but my fiance's mom is and omgosh she acts like her son is having a child at 15.. he's 22 and has his own place and she is still complaining..
I say write a letter she will be happy she having a grandchild at 1st she might be a Lil upset but it will grow on her the longer you wait the more she will be upset because you kept it from her
U should take her out to lunch... :) but y is it so hard? do u still live with ur parents?
Can you're dad help you talk to her? I would have my dad there to diffuse the situation..
