i feel the need to reply - i returned to work when my son was 12 weeks old - 3 days to a 7-5:30 job with 6yo and 3yo AND a new job i obtained after my son was born with a 2 yo and a baby 3 months older than my son.
Both have worked brilliantly for me and them, my salary didn't change, no did my hours while pregnant in my existing job. I had time of for 2 scans but made sure they were as late as they could be and offered to arrange cover with nanny friends.
I left work at 38w and my return date was pencilled in but kinda left 'open' but I soon decided the 12w was ready to go back, quicker I got back the easier it would be!
I take everything i need to work every day and I work 20miles from home. My salary hasn't changed. My charges LOVE my son, really miss him when he's at home with daddy (who works shifts) but 12/15 days he's with me.
I have bought a double buggy as the one at my new job is really heavy, I take a portable highchair with me and I make sure (well try) that all my stuff is in my car each night and tidy, no evidence of us around. There are odd times I've left a toy there but I do try and ensure that it is still there house - if that makes sense. They've taken their stairgates down, they don't have a cot - totally respect this its their house - I just make do, be vigilant - and for sleeps he'll sleep on the youngest bed or now he's getting a bit more mobile i've a travel cot in my car.
I bought a bigger car a month after returning to work! (7 seater) so I can get my 2 charges and son and buggy/scooter/bikes in my car, I was driving a micra, which was OK and useable but the new car just makes life easier
Having my son with me doesn't stop me/us doing anything that I didn't do previously - I am a LOT busier and have to be more organised. I have a great team of nanny friends who have been brilliant esp in the early days - they are very hands on with my son and take him off me to feed him n stuff so I could get on with giving my charge time n attention.
My son just fits in with work, he sleeps on/after the school run and after lunch now - but IF we are out and he doesn't sleep he (and I) have to cope- there have been days when he's had 20min sleep since 6am (when I have to wake him to leave for work)!!
its all been really smooth if I'm honest. Some things i need to think about - like swimming or cinema in school holidays - be it doesn't stop us - I drag along a nanny friend of palm my son off to someone for a few hours or plan it for a day he's at home with daddy.
The new job is a little more chaotic but there are only 3 months between them, and being new to the job anyway. Still I've just got on with it.
I guess i'm just trying to say it can work, it does work and my charges get a lot from it - they learn to share, they have learnt to be aware of where he is (esp now he's on the move) and what's around and more importantly they love him. they get the consistency of me coming back, I get a great job (with no pay cut) that I love and truly appreciate - and my bosses get someone back who know them, the family and we work well as a team.
My maternity leave was short, one of the reasons I decided this was to get back quick and incentive to keep me - they covered it with a mix of parents and nanny friends covering.
She's even considering keeping me when they're both at school and when (if) I have another baby which i think is a great salute to how well it has worked.
Hope that helps
