Yasin went through a stage like that for a while (I think it was at a similar age but I've got a shocking memory). I loved it - we got up in the morning, had a little snack and a quick play and then went back to bed together for another hour or two. I would say just go with the flow and resign yourself to not going out until the afternoon but if you don't love sleeping in like me maybe you could pop her in her pram/car seat after an hour for her nap so you can get out and about.
