Thanks for your science based and heartfelt based approach to baby rearing! We love it!!!”
What an interesting question! Particularly as I happen to have given a lecture on this quite recently. For those of you with a short attention span I’ll give you the conclusion first:
Yes, your own breastmilk is a good analgesic for your baby.
This has been shown in quite a few studies looking at the response of babies, both full-term and premature, to heel stick blood tests.
There’s actually been more than twenty of these studies and a number of reviews. The Cochrane Neonatal Reviews looked at all these studies and found that, though there were difference in the minutiae of the results, generally breastfeeding itself and, to a lesser extent, the taste of expressed breastmilk did relieve the pain of blood taking interventions.
The studies also showed the smell of the milk itself, even without the close presence of the mother or the feel of her breast on the baby’s cheek, was comforting. These associated factors are of course very important but with the sense of smell the familiarity of the odour of milk itself is critical. A Japanese study has shown that the smell of mother’s own milk (MOM) works to relieve the stress of a heel stick whereas another mother’s milk didn’t work at all and neither did formula. They measured the cortisol (stress hormone) level in the MOM babies and found it did not rise at all during a heel stick, but the level did rise without it.
One small point, I have to take issue with the supposition that Cameron is suffering from ‘teething’. There is a lot of good quality evidence to suggest that “teething causes nothing but teeth”. The most it seems to cause is a short period of minor discomfort at most (and some would even debate that).
