My baby girl is about to turn three. Not such a baby anymore. She is my little miracle, my rainbow baby. Conceived after a series of miscarriages, carried when the specialist team had told me there was only a 40% chance of me carrying a healthy baby to term. Birthed via emergency c-section when the epidural failed and left me able to feel everything. Raised as I have battled Post-Traumatic Stress Disorder and post-natal anxiety and as we made repeated trips to A&E and assorted tests when she suffered siezures which were absolutely terrifying as they happened, but have thankfully turned out to be harmless.

My eldest daughter transformed my life by making me a mother and teaching me the true meaning of unconditional love; my youngest has taught me about the tenacity of hope, completed our family and filled the hole in my heart. She has made me both infinitely stronger and infinitely more vulnerable than I could have dreamt possible.

Her third birthday is also going to mark the end of our extended breastfeeding journey. I never intended to feed her for this long, but it has been absolutely the right thing for both of us. She is feistily independent, and I love that nursing her is one of the few times she will completely relax into snuggles and into admitting a physical need for me. A couple of weeks ago she had a throat infection and became horribly dehydrated because it hurt her to swallow– breastmilk might just have saved her from hospitalisation. However, the time has come. I have talked to her about how bigger girls have their bedtime milk in a cup (like her sister), and she seems enthusiastic about that. Twice in the last week she has declined her bedtime feed; maybe I have already breastfed for the last time without knowing it. She is ready, and so I must be too. Part of me is. The part which would like some pretty underwear and a bit more freedom. But another part of me is very sad at the ending of such a wonderful phase in my life.

She moved into a bed last month, so I have already tucked a baby of mine up in a cot for the last time. She is well on the way with potty training; soon changing a dirty nappy will be a thing of the past (I might not be quite so nostalgic about this one). Her speech and vocabulary improves daily. I used to be Mee-mee, now I am Mummy, before I have time to blink I will be Mum. She loves going to pre-school three mornings a week so much that, from January, we will be increasing this to 15 hours a week. This will give me more time for myself which I badly need, mainly to get my writing career, which has been somewhat in abeyance for the last three years, back into gear. But it also means she will spend a significant proportion of her week away from me, and I know I will miss her.

That is the problem with her getting bigger. I know that all these last times are last times forever, because I won’t be having any more babies. While on one hand knowing that I am extremely lucky to have two healthy daughters growing up, I never expected parenting to be such a bittersweet series of tiny losses. Tomorrow I will lose my two-year old daughter. I know that the three-year old will be just as loveable, I know that there are many more adventures we can share as she gets older, I know that it is my job as her parent to encourage her development and independence – and I am so proud of every new little achievement.

Tomorrow I will put on my big-girl pants and I will blow up balloons and give presents and bake a birthday cake with a huge smile on my face as I celebrate the wonderful, funny, strong-willed, kind, determined and loving little girl that my baby has become.

But right now I just want to stop the clock and hold my precious baby close while she is still just a baby.
