She could have picked it up anywhere. Her dad was sick just before we left, we've been travelling on an aeroplane, she gets cuddles from everyone, and she keeps getting chances to gum other kids' toys. I've just let her go for it and given in to the inevitable.
On the plus side, as a sick baby she's pretty good. She sleeps better for starters. Just the other night she did a massive 10 hour sleep. Given that her previous record was 7 hours, and that was some time in the distant past, I was particularly impressed. Even better, I slept for 9 of those 10 hours.
Treatment has been breastfeeding, flushing out her nose with a little saline solution, and sleeping her in her car capsule, which keeps her semi-upright.
Fortunately, I've only had traces of the cold. It's a funny thing, before having the baby, I used to get sick all the time. Since having the baby, I have not had a cold, despite all the bodily stress and sleep deprivation, and despite that my baby and husband have had two. I barely seem to get the first symptoms before I'm better.
I have wondered whether this is somehow related to breastfeeding, because if I'm producing all these extra antibodies for her, then perhaps my immune system generally is more effective. An article from the International Breastfeeding Journal suggests there is some evidence that the mother's immunity is improved by breastfeeding:
A study of 43 breastfeeding women found that both breastfeeding and holding their babies without breastfeeding significantly decreased ACTH, plasma cortisol, and salivary free cortisol . In response to an induced stressor, cortisol responses were attenuated in breastfeeding women for a short time after feeding their babies. The authors concluded that suckling, but not breastfeeding in general, provided a short-term suppression of the stress-related cortisol response and HPA axis response to mental stress . They argued that this short-term suppression provided several evolutionary and biological advantages. It isolated the mother from distracting stimuli, facilitated the women's immune system, protected the babies from high cortisol in the milk and prevented stress-related inhibition of lactation. Based on their review, Groër, Davis and Hemphill drew similar conclusions . They noted that the neuroendocrinology of breastfeeding women possibly down-regulated the stress response. This down-regulation protects the breastfeeding mother and directed her toward milk production, conservation of energy, and nurturing behaviors.
Exclusive breastfeeding also increases the effectiveness of the mothers' immune system [50,51]. In a study of 181 women at 4 – 6 weeks postpartum, perceived stress, depression, anxiety, anger and negative life events were related to decreased immune competence for the formula-feeding mothers . This relationship was not present in the breastfeeding mothers who were protected from the harmful effects of stress on immunity .So maybe. Or maybe there's a placebo effect because I feel strongly that I just don't have time to get sick?
