大方の予想に反して、タカラは水疱瘡にならなかった。GPには「ほぼ確実に移ります」と言われていたし、アラタカラの生活は、スプーンもストローも食べかけのビスケットも、全てがごちゃ混ぜになっているから、移らないわけがない。潜伏期間を経て、発病しそうな時期にタカラのMMR(3種混合予防接種)が予定されていたので、不安で延期したほど。
胎児の時に母体からもらった免疫が効いて病気になりにくいのは、生後6ヶ月まで。ところが、母乳にも母体の免疫が含まれているから、母乳育児の赤ちゃんは半年を過ぎても病気をしにくい。そうです。タカラはまだおっぱいを飲んでいるのよ。医者の友達もこの説が当たりだろうと言っていた。母乳の質は赤ちゃんの成長に伴い変わっていくというが、1才過ぎて、どれ程の免疫力が含まれているものなのか、科学的な根拠がほしい気もする。
とにかく、母乳ってすごいんだと実感した。本当は、アラタの時と同様に1才でやめようと思っていたのに、止められず困っていた。アラタは真冬に卒乳して、直後にナーサリーに行きだして、風邪や感染炎ばかりもらっていた。母乳を止めていなければ少しは違ったのかしら。試しにタカラの断乳は春まで延期することにしよう。
アラタの水疱瘡を診察したGPは、タカラがまだ母乳を飲んでいるなんて思いもしなかっただろう。英国は最低半年間の母乳のみ育児を奨励しているが、実際に母乳を続ける人は、生後6週間までに半分弱、6ヶ月までには1/4に減るそうだ。対照的に、日本人の中には3歳過ぎても上げている人がいたりする。
日本社会では、根強い偏見のある帝王切開(自然分娩が「正しい」みたいな)と同じぐらい、母乳育児が「正解」だからなのだろうか。日本のサイトを見ると「1歳ぐらいまでは水疱瘡に罹りにくい」とあるが、母乳育児が多いことの反映かもしれない。ちなみに、WHOは2歳までの母乳育児を推奨。

Against all odds, Takara didn't get chickenpox. The GP who saw Arata told Jason that Takara will most likely get it. The life of Aratakara is so mixed up. They use each other's spoons or straws, and eat the biscuit other one left half eaten. I also expected Takara to get it and I even canceled his scheduled MMR 2 weeks ago, as I wasn't sure if it's ok to have MMR even when he was about to break out chickenpox.
Antibodies from mother last for 6 months from birth. But breast-fed babies keep getting antibodies from mother's milk and they tend to get less sickness even after the first 6 months. Probably that's the key. Yes, I'm still breastfeeding Takara. My friend Detlef, who is a doctor, also thinks this is the reason. I wonder if it is proved scientifically? I remember that the quality of breast milk changes as baby grows. I wonder what sort of goodies are still contained in the breast milk after 1 year?
Anyway, I'm so impressed by the natural human milk! To be honest, I've been thinking about stopping it, as I stopped for Arata at around his first birthday, but I just haven't been able to. Arata stopped taking breastmilk in the middle of winter. Soon after he started going to nursery and he had so much colds and infections. I wonder if I hadn't stopped breastfeeding, it might have been different? I think I will not stop breastfeeding Takara till next spring. (Unless he weans by himself.) Let's see...
I'm sure that the GP who saw Arata's chickenpox didn't expect Takara still have breastmilk. NHS recommend exclusive breastfeeding for the first 6 months. But in fact, less than the half mothers still breastfeed when babies are 6 weeks, and till 6 months, the number drops 1/4. On the contrary, I have a couple of Japanese friends who were still breastfeeding when their children were over 2 or even 3 years old.
Probably it's due to different social expectations. In Japan having babies by c-section is still regarded as 'not proper birth'. (They believe women must suffer great pain during child birth!) In the same way, breastfeeding is the 'right' answer and lots of them think there is no other option. In a couple of Japanese sites say 'Children under 1 year old don't usually get chickenpox.' This must be based on the fact there are a quite number of 12 months old still breastfed in Japan? WHO recommend breastfeeding for the first 2 years.
