I’m an only child of parents who are both only children, my husband is an only child too. We have identical twin girls aged 5. I’m dealing very badly with the bickering, refusing to share, wanting what the other one has got and competing for attention. I also equally get irritated with them whipping each other into a frenzy of giddiness. I grew up in a quiet house and I cannot relate to their squabbles and volume. I have had depression (now treated) since they were born. I want to be a good mum but can’t seem to be anything other than shouty and bad tempered and I can see that they are copying me now which is obviously awful. Help!
