I am due in 10 days and with a very busy 4yo in the house I think it may be very different this time round!
Last time, dd would wake about 7am, I would bring her into bed and feed her, put the radio on (DH would make me a cup of tea before leaving for work, and bring it up - luxury!), and then drowse until around 10.00 when she'd want feeding again, so I'd do that.
Then she'd doze off, I'd get up and have a quick shower, and potter until she woke again and wanted more feeds.
Then we might go out, or I might sit and watch TV or read while she lay in the Moses basket, or on me, or on the playmat (it was a nice big comfy one). When she started to be a bit more awake (at about 4 weeks) I started to lie on the floor next to her while she was under the playgym and bop toys a bit.
But I always spent ages changing nappies, chattering away to her. And loved cuddling her when she was well-fed and sleepy. And suddenly I'd find half the day had gone. I found it hard to get out and do things, but I think that's because I have always been very happy in my own company and was quite content pottering at home. And she was very placid as a tiny baby, which meant she was happy lying in her Moses basket waving her arms and legs around.
She's now grown into a very busy, sociable four year old who wants to know 'what fun are we going to do today?' so I think it may be less quiet, peaceful pottering and more 'Come on kid, we're off out, your sister is going crazy....'
