Tom Cruise and Katie Holmes’ campaign to convince the world they are a normal family has taken a hit in the form of questions over their parenting skills.

‘Experts’ have taken the A-list couple to task over recent pictures that show that daughter Suri is still being bottle fed at aged 2.

"Most pediatricians recommend a bottle should be given up by age 1 - almost certainly by 18 months," say Dr. Charlotte Cowan, author of the Dr. Hippo book series.

The Doc suggests to Usmagazine.com that the family's constant travelling could be a factor in Suri's reluctance to give up the bottle.

"When babies are challenged, their diet is upset, their sleep is upset," Cowan tells the mag.

"They will regress back to previous habits...lingering with a bottle is comforting. You could argue that her parents have decided that this is not the time to try to wean her off if they're traveling frequently."

However, psychiatrist Dr. Keith Ablow believes that Suri's habit is not harmful to the adorable tot.

"We don't have a wealth of experience that suggests from a psychological point of view children are harmed by using a bottle for too long," he says.
