Ben and Max’s sister, Molly, is four weeks old. We have survived a month with three children, something which feels like no mean feat.

That seemed unlikely after our first family outing one week in, when we made it just 100m from our front door before Max broke the rules about how far ahead he was allowed to go on his bike, we shouted, he started crying, Ben started crying because Max was crying, and we all went home. Since then we have managed a family swimming trip and some less eventful local walks. So we might actually be capable of leaving the house as a family of five.

Both boys have been unbelievably sweet with Molly, and very tolerant of the disruption and imposition involved in having a new-born sister. Through a combination of James having a month off work, numerous carers and family members helping us out, and a baby that sleeps a lot, we have been able to keep things as routine as we can. Ben has shown once again that he can cope with a lot of change and take it in his stride, while Max has been demonstrating his capacity to be both a kind big and little brother. We have all had a lot on, but we’re doing okay

We do not approach birth lightly. Ben’s disability is because of problems during his birth and we therefore know too much about the risks of things going wrong and having lifelong implications. Max was ill immediately following his birth and had to be admitted to NICU. We sort of assumed that our third baby would end up in NICU, even though a neonatal consultant took the time to explain to us how (very) likely it was that we would have a totally healthy baby.

One of the people who really understood our concerns about the birth of this baby was the obstetrician who we saw throughout this pregnancy and who had previously delivered Max. She is someone we have huge respect for, whose judgement we trust, and who had successfully guided us through my second pregnancy when we were at our most anxious about having another child.

This time we knew in advance that she would not be able to deliver the baby because the elective caesarean was booked during the Christmas period when she would be on holiday. Another obstetrician would do it, it would be fine, we told ourselves. As we prepared on the morning of the birth, getting in to gowns and talking photos of my puffy face, we were calm but nervous. And then she popped her head round the curtain to say hi. Dressed in jeans and tshirt, she was officially on holiday but had come in specifically to do my caesarean section.

That, there, is an emotional moment: the joy of knowing we were in her hands (literally in my case), that our baby had the best possible chance of therefore being fine, that someone so thoroughly understood how difficult this all was for us and had come into work especially.

And then Molly was born, screaming before she was out of my womb, to be immediately declared, with a thumbs up, totally and utterly healthy by the neonatologist we had demanded be on hand to check. No resuscitation, no breathing difficulties, no-one at all worried about anything. She breastfed immediately and, following the facilitation of the obstetrician who knows we spend too much time in hospitals, we were able to go home the following day. You would not believe how uninterested everyone is in a healthy newborn baby – barely any observations, no-one came to check her overnight. If you hadn’t had experiences like ours you would have no idea of the anxiety and stress lurking just across the corridor in the neonatal unit.

We have now had four weeks of admiring and nurturing little Molly and she is a delight. Third time lucky, we had a baby who didn’t need a canula in their head, or a tube in their nose. She immediately breastfed and sleeps like a champion (just not always at night-time). We take none of this for granted – it is luck of the draw whether you have a baby that does the basics easily or not.

We have not lost and will not lose sight of what a privilege it is to have her here with us, healthy and thriving. Nor what a delight it is to share this baby girl with these boys of mine. We are all lucky.
