6mo has had a bad cold (first one) since Friday, get on Sunday, GP checkup on Monday, all fine. He's not fed as much (mostly formula fed with a little bit of breastfeeding, about 80% of what's normal, not weaning yet) so he has fewer wet nappies. He hasn't had any dirty nappies since Sunday though which worries me - he normally has 1-2 a day. I know it's quite normal but I could really use some advice/reassurance. I'm sure it'll come but worried it will be hard and painful when it does. We've tried baby massage, the bouncer, will take him for a drive later. Just waiting for a call back from the GP now - I guess they'll prescribe a laxative. Is there anything else we can do?
