My 14 week old DD has always been slow to gain weight (no more than 6 oz a week and has only put on 3lb since birth) but has slowed down to just 3-4 oz a week for the past 3 to 4 weeks. She totally refuses to take a bottle (have tried every teat/position/time of day)so can't top her up with formula. Have now resorted to waking her for a dream feed at 10ish. This is particularly galling as she had recently started to sleep 6.30pm until 3ish, allowing me to get some much needed sleep. Has anyone else with exclusively BF baby had problems with weight gain? I'm worried putting on so little weight will affect her physical development.
