ds having trouble doing a poo.....sorry

[aristocat]

hi all,
my DS is 7yo and is having trouble doing a poo. this is the first time ever and only been since yesterday, i have given him some lactulose today to help but just wanted some good advice.

he does eat fruit and vegetables every day - what can i do to stop it happening again.

sorry if too much info.....

I've heard glyerin suppositories recommended on here before.

Also lots of water and running around and avoid chocolate, bananas and eggs as they are 'binding'.

I think the lactulose will take a while to kick in, iyswim.
