Is my baby sleeping too much? She's 8 weeks old and she'll sleep from around half 10/11pm to around half 7am ish am she'll stir in the night but isn't hungry, she'll sleep next to me and go back to sleep, she'll have a 6oz bottle and around 10am ish she will go back to sleep in her chair for 20mins or so and then wake but then she's crying because she's tried (refuses bottle) and then she'll go back to sleep only on my chest till around 3pm ish but then she's awake smiling and 'playing' from then to about 6 have about a 20/30 minute nap and then awake 'playing' till 10/11pm
Is this too much sleep? Because obviously I'm a little worried about her not having enough bottles but she's putting weight on still, any advise is welcome
