It seems like it was just yesterday that Rochelle Humes announced she had given birth, doesn't it?

But, as you can see from The Saturdays singer's latest Instagram snaps, baby Alaia-Mai is growing up fast - she's inquisitive, she's sitting up and she's growing her hair out.

The first image Rochelle posted was of her little girl sitting up in bed next to father Marvin with a dummy in her mouth.

Rochelle captioned it: "My bed looks like this right now #noplaceidratherbe"

N'aww!

The proud mum also shared a snap of the little girl playing with her toys, dressed in a sweet stripy romper suit.

She captioned the snapshot: "Her hair is growing"

Alaia-Mai will celebrate her first birthday next week and Marvin revealed to OK! that, while it's a big milestone, he and Rochelle won't be going overboard with the birthday celebrations.

"It's not going to be big, she's only going to be one… it's not a wedding!"

Whatever they decide to do, we just hope there's lots more photos - Alaia-Mai is just so cute!
