Your toddler is very aware of everything that goes on in the family. If he sees Mummy quarrelling with Daddy, he’ll feel confused, troubled and upset. At this age, he’s extremely sensitively to parental disputes.
If at all possible, don’t have a blazing row in from of your two-year-old. It doesn’t matter who is in the right and who is the wrong – sort out your disagreements when he’s not there.
Wait till he is busy playing in another room, or better yet, hold your argument until he’s fast asleep at night.
