Fruit juice causing bad belly and behaviour?

[sarahscotty]

My 2 year old has had a runny bum for about 4 weeks but feels well otherwise.

The only other thing, his behaviour has been awful for the same amount of time. He's been quite uncontrollable and whinging an awful lot.

As he won't touch milk, we started giving him a small carton of orange or apple juice in the mornings with a breakfast bar or toast.

Do you think this could be what's causing it?

I feel so stupid I never realised juice caused this.

Has anyone else experience this?

It could be the juice. If he won't touch milk though, it could be an allergy to milk in food as that can often cause diarrhoea and poor behaviour.

@BunnyRuddington hello no he hasn't drank milk for probably a year and we didn't have this issue before - only the past 4 weeks or so.
