My DS is now 20 wks & was sleeping for upto 8hrs from bed time a few wks ago, the last few wks he has seemed very hungry constantly chewing on his thumb, hand or anything! & is BF more often & waking again after about 3 hrs, i have been thinking of starting him on some baby rice to try to satisfy him? he arrived at 34 wks at 5lb but is now over 14lb, i know the rice has less calories but wondered if it would help settle him? had planned to do BLW from 6 months. He also may be teething? though not sure & did have a cold but this has gone now. Any thoughts??
