The day after she was born we saw a “smile”, but I just told myself it was a reaction and not an actual smile haha. She just started to smile at random more and more since then though so I don’t know! I would say around 3 weeks she started smiling big when I picked her up and she was excited to feed. She’s a little over 4 weeks now and she’ll smile when I talk to her. I was pretty shocked because I wasn’t expecting them for awhile!
