My little 2 month old

Time flies or it could just seem like that now that I'm getting some more sleep at night. Holly is now 2 months old. She sleeps 12-16 hours a day. She eats every 3 hours during the day & every 4-7 hours at night. She is finally starting to wake up happy & is spending more time smiling now. This month she had her first haircut, attended her 1st birthday party, had some play dates & has been such a joy to have around except when she is screaming at me because she is angry about having to drink a bottle.
