girlfriend, ive got 2 kids and they all develope differently. dont stress. I remember worrying about the same thing when my oldest was 14 months old. Now shes 2 1/2 and i wish she would just shut up for like... 5 mins.
Ahh... relax.. once she starts really talking your be wishing for the days when she couldn't. ;D
Those will be the days when she didn't repeat curse words you said when something bad happened right in the pediatrics waiting room at the doctors.
The days when both of you were up at 5 am because of the baby and she hasn't stopped talking since the second your eyes opened after you've only had 3 hours of sleep.
And lastly, the days when you were able to talk on the phone or to your hubby at the dinner table without her constant jibber-jabber int he background thats nearly impossible to talk over.
Trust me, you'll miss the days when she couldn't talk. Enjoy it while you can!!!!!!
Side-note: I always appreciate advice from other parents but I believe that you always need to remember what is ultimately right for you as a parent. Consider the advice, but take it grain of salt, and use your knowledge to decide the right course of action for you. Even if everyone else doesn't agree with you. ;)
