Hilary Duff just shared the cutest photo of her baby girl as she turns four-months-old

Absolutely adorable.

Four months since Hilary Duff gave birth to her first baby girl, Banks - the star is marking the milestone with the cutest snap possible. Lying on the bed in a set of pyjamas, the mum-of-two captioned the photo:

"Sunshine bright light was 4 months yesterday! My little pixie is getting big nomnomnom"

Talk about DOTEY. Since giving birth, Hilary has spoken about the challenges of moving from one child to two and the importance of rewarding yourself for being a hard-working mum because "you deserved to be praised" and the little things you do don't go unnoticed. Now heading back to work since giving birth, Hilary is back at Paramount Pictures filming for her series, Younger. But it wasn't long until she got a surprise visit from her number one fan, who she's obviously finding tough to leave at home. N'awwh. Younger just started production on its sixth season, which is set to air this summer.
