ds is exclusively bf. however in the past 2/3 weeks he has become very hard to settle to sleep at night and after sleping right through from about 6 weeks has started waking 2-3 times during the night to feed. he is teething at the moment and i know he will be having growth spurts aswell and that the only way to encourage my supply is to feed him but i am totally exhausted by this at the minute and i hae no energy to do even the simplest of things with my older ds (4). i dont want to have to supplement with formula unnecessarily, but i dont want to start him on solids too young either. does anyone have any advice or should i just keep doing as i am?
