On the 1st of December, one day before her 4th month mark, our little bundle of joy just could not contain herself any longer! I don't know how I discovered this particular noise or why she thought it was so funny, but she did and it was adorable!!
I read that most babies start laughing between 2-3 months... so either shes tough to please or I'm just really dry lol.
Side note: I tried the same noise on her the next day and it had no effect. Well, I got some gurgling and she tried to avoid my gaze... but no laughing :( I guess I'll have to find something else that'll make her laugh!
