DS is 20 weeks on Friday, weighs 15lb10oz and is solid and chunky. Until last week he was sleeping through the night with maybe one moment of self settling in the night. He's also been close to teething (I think) plus had a cold (which is finished).
Over the Last couple of days while seeming well in himself he's lost all interest in milk? He's barely taking half what he normally would. Is this a sign to wean ??
