I'm about 9-10 weeks pregnant and DD 21 months still feeds on demand pretty frequently day and night in addition to a good diet.
But lately she's been having a few mouthfuls, then complaining it's "hot"! 
I've checked that there are is still milk there (never been able to express much but droplets come out still on a quick squeeze)
It's not stopping her, I'm not worried - just curious! Any ideas?
