The nightly teeth-cleaning battle, the bedtime routine and the dreaded school run are among the most stressful things about parenthood, a study has found.

A poll of 2,000 parents found the average mum and dad spend almost two hours a day feeling stressed, with trying to keep the house tidy the most common cause.

Others feel the strain at bath time, while trying to get children to behave in public and shopping for new clothes with the youngsters in tow.

Mornings – complete with getting the children out of the door for the school run, persuading them to finish their breakfast and clean their teeth – are the most stressful time of the day, claiming five of the 10 top stresses.

Dr Linda Papadopoulos, who has been working with belVita Breakfast to help relieve parents, particularly in the mornings, said: “The stress and challenges of parenting can feel overwhelming – especially when we feel under pressure to get a lot done in a short space of time.

“Morning can be especially challenging and it’s key to develop a positive, convenient routine in the morning as it sets the rhythm for the day.

“When it’s ‘back to school time’, trying to get everything done and leaving the house on time is at its most pressurised so developing strategies that you give you and your family a sense of control is really important.”

The study by belVita Breakfast of 2,000 parents of school-age children, found that staying on top of the house chores is the biggest cause of stress for mums and dads, while getting the children to do their homework and the bedtime routine are also big triggers.

Researchers also found the average parent spends one hour and 48 minutes of each day feeling stressed, with 63 per cent going as far as to say the majority of their stress is parenting related.

Mornings are the worst time of day for parents with the average mum and dad having at least one day a week where they struggle to get out of the front door on time for school and work.

The children taking too long to do things is usually to blame for the family’s lateness, followed by youngsters not doing as they are asked and not getting out of bed.

But as a result of the frantic mornings, one in five parents has dropped the kids off at school after the bell and the same percentage have ended up late for work as a result.

Others have given the children lunch money instead of a lunch box, sent them to school in dirty or un-ironed uniform or with wet hair.

As families prepare for the dreaded ‘back to school’ week, it’s not just kids who bear the brunt of the ‘morning madness’, with over a third of parents forgetting breakfast and 38 per cent having a fight with their partner over who takes on the most in the morning.

Eighty-seven per cent even said they look forward to the weekends when they don’t have to worry about the school run and leaving the house on time.

It also emerged that 66 per cent of parents believe mums bear the brunt of the morning and back to school stress, with half admitting they often argue with their partner about who gets the raw deal.

Daniel Kessler from belVita Breakfast said: “We believe a good morning can set you up for the day – doesn’t mean it’s always that easy! However, what the research shows is that parents are looking for ways to feel more in flow and help their routine.

“belVita is a tasty and convenient breakfast option, meaning you can focus on getting the family out of the door but able to make sure you can cover off your own morning must-haves.”
