My only dd is now 4 and starts school in Sep. Personally, it seemed that we (myself and other mummy cohort) all went into a 'baby zone', a kind of baby-sentred fog that seemed to start clearing when they approached 2ish. Then the other mums all had more babies and went back into the zone while I feel I am now leaving the baby zone completely.
For 4 years my social life has revolved around meeting up with my mummy friends - 9 in particular. Two are still gearing up to their second baby (dcs are younger than mine) and all the others have another one or more. I feel a little out of sync now as I am increasingly readjusting my life - in many ways - it feels as though I'm getting my life back.
I'm in a kind of limbo - neither fish nor fowl - neither a full-time working mum with work colleagues nor a mum with preschoolers. Having an only, I've got to this stage years ahead of the others. I think I'm also temperamentally more welded to my work, which is also a bit out of sync.
