Alongside the fresh-faced image, she wrote: ‘3am is when I do my best online shopping! Truly though, I look very happy in this picture and these moments in the middle of the night are precious ones that I am forever grateful for..
‘But I definitely don’t want to sugarcoat how challenging I have found breastfeeding so far. Maybe one day I’ll talk about my experience with it.
‘But for now I just want to say greatest respect to all the mothers out there figuring out their way to feed their baby, it’s a tricky journey and I’m so grateful for the support I’ve had from the NHS and of course from @jamiejewitt_’.
