I try to get out at least once a day (we have a dog to walk too), and as often as possible I actually get out and meet a friend for coffee, go to my mum's group meeting, etc. That gives DD some different people to look at and, increasingly, interact with.

Other activities I was doing when she was about the age of yours (gee, it's only a couple of months ago and it feels like forever) included:

- giving her a bath

- as much tummy time as possible

- as much nappy-free and general naked time as possible (our heating bills this winter are scary!). This helps her discover her own body more easily. Lots of rolling her around on the floor, so she can feel what different positions feel like, even before she could do them on her own.

- lots and lots of talking to her and letting her watch my face as I say things. She was so fascinated by my face, and increasingly interactive with her expressions and the "words" she said

- sitting together and reading a book (or a magazine, or a webpage, or anything really - it's not like the content matters much at this stage, but never too soon to start reading). She started looking at the pictures by the time she was 2 months old, and since 3 months she has been interested in turning the pages of board books (not that she's very good at that yet...)

- walking to the shops

I tried to do a different main activity on each wakeup, so 5 or 6 of those a day, most of them repeated each day. It does get boring, though. I can sympathise. Getting out to meet with other mums helps a lot, so if you can get to a parents group meeting or a playgroup, or just meeting people in the park, that might help relieve the tedium.
