The former glamour model referred to a recent study that suggested breastfeeding actually increases the risk of asthma.
This is despite NHS guidelines that recommend breastfeeding as the preferred way to feed newborns as long as the mother is healthy and able to.

Katie wrote in her weekly magazine column: ‘A new study says breast milk’s no better for babies than a bottle and claims it increases the risk of asthma. I’ve never breast-fed because it’s nice for dads to be involved in feeding too, but I’ve been made to feel guilty in the past. My kids turned out just fine!’
Dr Cynthia Colen told the MailOnline earlier this year that focusing on the importance of breastfeeding may be pulling focus away on other things that could improve the health of a newborn.
She said: ‘We need to take a much more careful look at what happens past that first year of life and understand breastfeeding might be very difficult, even untenable, for certain groups of women.’
The doctor continued: ‘Rather than placing the blame at their feet let's be more realistic about what breastfeeding does and doesn't do.’
Both Katie and Dr Colen’s comments contradict NHS guidelines and years of previous research that seems to suggest that breastfeeding has numerous benefits such as helping build your baby’s immune system.
Though women are encouraged to breastfeed, it has more recently been emphasised that should women find themselves unable to breastfeed they can still give their baby the nutrients he/she needs through formula.
