I've just been to see the health visitor with my 12 week old DD. I've noticed lately that her weight gain has slowed down and she has now moved from the 50th Centile to just below the 25th. She seems very well and alert, and has been sleeping from 7-8pm through til 6-8am since she was about 9 weeks. The health visitor wants me to start waking her during the night to give her extra feeds! I really don't want to do anything to jepordise the brilliant sleeping pattern she has developed, but obviously I'm worried about the slow weight gain. Has anyone had a similar experience - or have any good advice to offer whch doesn't involve a return to sleepless nights??
