6 weeks Already?!?!

I cannot believe. My baby is 6 weeks old already. Where has the time gone? She has gone from this little fragile thing to a little baby that is trying to hold her head up. She is more alert during the day and recognizing voices. I am not exactly sure how far she can see but she will follow Kenny's voice across the room and move her eyes and head with him. It is amazing how much happens in just the first 6 weeks. Ava was holding her head up completely by 8 weeks old and I think Hailey may be on the same track. She is getting stronger each day and bounces her head all around when you are holding her. We are giving her more tummy time on the play mat. At first she didnt act like she was too thrilled about it but now when she is a little fussy, tummy time will actually calm her sometimes. She is now eating 4 ounces every 3 or so hours during the day and at night she can sleep a stretch of 5 to 6 hours and then will go back to every 3 or so hours. The long stretch is nice because I actually get 3 or 4 hours of the 5 or 6 so I am not a total grump in the morning. I have started putting a little rice cereal in her bottle, it seems to help keep her full and make her a little happier. We have had some gas issues with her, changing her formula and adding gripe water has seemed to help a lot more. She still has some of her fussiness but its a little here and there instead of a large block of time. It has helped a lot in the stress department. She seems to be fighting her sleep a little bit. She will eat her 3rd bottle of the day, in the late afternoon, and will cry until she falls asleep. It can be a handful with Ava but my patience has stayed with me and I just work with her until she falls asleep.  We have been relying on the swing more and more. She seems to really enjoy it. She sleeps in it during the day when we are all out in the living room and there are times she will wake up and just sit and swing, watching her surroundings. Ava will go and talk to her and bring her toys. It has helped a lot when I am on my own. I am so waiting on her to hold that head up on her own so she can sit with pillows around her and enjoy playing on the floor a little more.
