I remember the first feed like it was yesterday.

That tiny, alien creature, all purple and waxy white, placed upon my exhausted body as I lay on our bed at home, high on gas and air and the enormity of what I had just achieved. Holding my baby close, the baby that for the past nine months had lived inside me and for the past nine hours had pushed me to the limit, feeling the unfamiliar suckling at my breast.

I had hoped, before he was born, to feed him for a year. When I realised, as his weight began to plummet over his first few days on the outside, that things would not be as straightforward as I’d planned, I hoped that maybe we would make it to six months.

But tongue tie sorted, and after several weeks of learning from scratch how to carry out this most natural of functions, we sailed past that first milestone – and just kept on going.

He fed at least three hourly, night and day, for two years.

It was exhausting, but it felt so right. I was proud to have overcome those initial obstacles, to have figured out how to make breastfeeding work for both of us, to have mastered the art of feeding in the sling – to have written two novels with him nursing there.

I did wonder though, after that second year, whether he would ever stop.

That was my adjusted goal, in line with WHO recommendations: to “continue breastfeeding up to the age of two years or beyond”. And then as that new deadline approached I decided to let him lead the way as far as weaning was concerned.

I wasn’t expecting him to go quite so far “beyond”…

We had a few shaky moments, soon after he turned two. However gentle and respectful my parenting aspirations I really, really needed to get some sleep. But then just as I thought I might need to make the decision for us he decided he didn’t need to feed at night any more.

Daytime feeds continued, every three hours.

As we went into the fourth year, that eased off. It would be just twice a day, before his nap and at bedtime. And then just for his nap. And then sometimes not even for that. He would go a day or two or three and I would think perhaps we were done, and then he would ask again for booba and I did not say no.

I often asked him, in those last few months, if there was milk. It was hard to believe that my body could be so adaptable, keeping up a sporadic supply for as and when my boy decided he needed it. But he assured me that there was, and sometimes I still felt the letdown, the rush of oxytocin.

I miss that, a little, now that he has stopped.

I tried to remember to take photographs. It was easy in the early days (once I’d got over the initial insecurities), but my confidence dimmed again as he got older. Our society does not take kindly to the image of a preschooler on the breast, however much a nearly four year old is well within developmental norms to be not quite weaned.

Still, I captured a few. I am glad to have them now: those pictures of the (almost) last feed.

The actual last feed passed unnoticed. I suspect it was a naptime, one afternoon when I snuggled beside him in his bed as he fought against the tiredness permeating his little body. Perhaps it was an afternoon when I dozed off, too: enjoying having my child close, the whirlwind of energy temporarily stilled.

It is a strange feeling, knowing that I won’t nurse my child again. I can already feel a levelling out in the relationships in our family: my husband has been so incredibly supportive of our sustained breastfeeding journey, and part of me is so happy that there is no longer that imbalance in our parental roles.

There is at the heart of it all, though, a sense of loss.

Something happened last night that brought it to the surface, made me realise that we are in the midst of a powerful transition.

Arthur’s cries startled me from sleep at about two in the morning. He very rarely wakes at night nowadays, and it is even rarer that he calls for me. But he was: shouting “Mama!” with increasing urgency. I leapt out of bed and down to his room, and found him kneeling on his new cabin bed peering into the almost darkness.

I searched out his eyes and held him close, his little body shaking. I asked if it had been a bad dream and he nodded, head still nestled in my neck. I wanted to ask what it had been about but I didn’t: I waited.

Moments later he pulled back and looked at me.

“I dreamt you died, mama. I dreamt you died.”

I lifted him out of the bed and we snuggled on his beanbag. His eyes wide open and breathing shallow as he rested his head against my chest, my hand gently stroking his hair and reassuring him that I was very much still there. Every now and then he would ask, “Why did you die, mama?” I didn’t know what to say, so I held him closer.

I felt my breasts fill with milk, but he did not ask to feed and I did not offer.

After a while of lying there I asked if he would like to come and sleep with us or whether he would prefer to go back into his own bed. He stood up and walked across the room, climbing the ladder up to his bed as I hovered close behind. He pulled the covers up to his chin and looked at me, smiling when I said he could come to us at any point if he felt scared.

He closed his eyes and went to sleep and I went back to my own bed and lay there in the almost dark, thinking.

In his world, one where he has been nourished physically and emotionally at the breast for as long as he has been alive, I suppose a piece of his mama has died. I am still here, though, and I can still comfort him.

Things will just always be a little different from here on in.
