My brother has just had a beautiful baby with his wife (almost 4 weeks old) and they are very appreciative of the fact he sleeps so well. Perhaps I am just jealous but I have seen him on regular occasions for long periods of time and he is probably awake for about 30 minutes a day in total, including nights, he doesn't really make much eye contact, isn't looking around at his surroundings. he wakes up about every 3-4 hours for a feed, but even then will just whine a little and then go back to sleep. he stirs when you strip him off to get changed but doesn't wake fully. He has been like this since he has been born. Is it something you would be worried about or am I just being silly?
