...Unless you count the admin/call centre stuff I did before dd1 was born. 
I'm seriously thinking of applying to my local uni to do an MSc in Occupational Therapy (there was another thread about this the other day if it sounds familiar)
The thing is, I'd always imagined I'd have 3 dcs, and i'm struggling to see exactly how i'm going to manage this, given that my masters will take up two years, (starting next Feb if i'm accepted), then I'd like to work for at least another year after that, before taking maternity leave, which means I'd be nearly 34 by the time I'd be ready to have another baby. I know that's not ancient by anyone's standards, but dd1 would be nearly 8 and dd2 would be 4, and I'm not sure about the pros and cons of having them so spread out, and that's assuming dh and i don't have any problems concieving.
Or, I could put the whole idea of having a career on ice (again) and concentrate on getting knocked up (again) so the dds have a sibling closer in age to them than they would otherwise.
I know my problems are quite silly really but if anyone else has been grappling with similar stuff, or thinks they know what i should do, i'd welcome hearing about it.
