My boys are now 17 weeks (8 weeks corrected) they tend to sleep most of the time, but when awake just cry, its as if they dont know what to do and get tired. Both have heart murmous and are seeing a specialist next month. They feed 4 1/2 oz every 4 hours although go from feeding at 7pm till 3am then go until about 7am, 10am, 3pm. They now weigh 10lb11 and 10lb14 and are about 55cm have started smiling and cooing, enjoy their baths and love their big brother (17 months) will watch him, although dont really look at each other. I am curious as to how different their development is to other September babies. They have good head control and sort of like lying on their tummies. Their only problem is when awake they just cry only have about a 20 min happy spell. Seem to make each other cry as well. Am starting them on some precription milk today to see if their crying is due to that and am making an appointment to see a Crainial Osteopath (is that how you spell it) They are so diffrent to how my first son was he wsa full term. Will be weaning them next month I think, as you go by their birth date. My HV has been helping me loads with them. Any feed back appreciated.

had to look up cranial osteopathy

my sam is 16 weeks and unlie some in this forum he's not really trying to sit up on his own. he's quite happy on his back. he'll go on his tummy but doesn't seem to like it for too long. he's a happy baby but very fidgety. i have to keep him stimulated or he'll cry like your boys, which leaves me with little time to myself ... hats off to you coping with three kids under 2yrs!
