With DD I spent the first four months dealing with undiagnosed reflux and CMPI. So it wasn't boring, just awful! I'm so sad we couldn't enjoy that time more. Then she got medication, we went to sleep school and she was a dream baby. But by then I had anxiety which was pretty out of control. I don't really remember what I did all day but it was probably boring! I hardly socialised as I was so worried about messing up her routine. At 9 months I got medication, went back to work 2 days and everyone was happier all round
This time with 2 kids I'm loving it. DS is a totally different baby, I've got a lovely mums group, my parents have retired so I have heaps of company not to mention DD to keep me entertained/drive me mental.
My only piece of advice which I have learned after having 2 is to try and do your chores while your DS is awake. Eg Cleaning the bathroom - pop him in his bouncer and he can watch you. Tidying outside - into the baby bjorn and off you go. Then rest when he does. Means you get some time for yourself and keeps home entertained while he is awake gets harder with an older more mobile baby who isnt quite so content just watching but wants to join in and 'help'.
