Sharon,
I agree, the smiles are a heart melter.
BJ gave us a few early on (at 3 weeks...which we assumed were wind til the health nurse saw him smile on day when he was looking me in the eyes, and she said they were real).
The other morning, DH was cuddling him while I got ready to go out and he got 7 in a row wile talking to him...oh my god so gorgeous.he just won't do it when the camera comes out....he goes all serious!
BJ seems to be almost trying to cut out a feed at night (which is great, but confusing!), he feeds about 9:30 or 10pm, then has been going through til between 3 and 4, then through til 8 or 9....rather than waking at 2 and waking at 6.
Whilst this isn't a problem, it makes mummy confused about trying to squish in another feed or not!

Also, we had him set to an 8:30pm bedtime which meant DH would see him for about an hour when he got home from work, just meant we had a late tea as we wait til he settles first before cooking and eating. BJ has decided on a 7pm bedtime....Poor DH doesn't get home til about 7:30pm!
