I think it would be extremely hard to manage what you are planning on.

I have a 4 week old baby and normally work in a partitioned office area similar to what your's sounds like. There's no way known I would contemplate taking my baby into work with me in 8 weeks time. I'd get very little work done.

Briggsy's girl is right - you are planning around a perfect baby scenario. The reality is likely to be quite different.

I planned on breast feeding - I was 100% determined to do it. My baby ended up in special care due to an infection on the night he was born. He also ended up under lights for jaundice. He had attachment issues, still does even though he's been well now for 3 weeks. I am not producing enough milk to just use expressed milk. Didn't plan on any of these issues and breastfeeding got very difficult because of it all. I have to express and then bottle feed the EBM to him then top up with formula. This takes time. If I was at work it would take about 1/2 an hour for each feed (including burping & nappy change), so probably an hour and a half a day would be lost to this.

Then there's the clothes changes (for me and bubs when he projectile vomits, or just has a bit of an overflow), the nappy changes in between feeds and the time spent popping his dummy back in his mouth to calm him down (wasn't planning on using a dummy either). More time is spent on cleaning his face when he dribbles milk, cleaning gunk out of his eyes several times a day and just soothing him when he's upset. Couldn't guestimate how much time this would take up, but it would be a considerable amount of time.

Trying to get 8 hours of work done in less than 8 hours will be stressful. Stress can effect your milk supply and cause issues with feeding. Adding extra time on at the end of the day to make up for it would be exhausting. If you didn't manage to do all your work it would cause problems with coworkers.

You are likely to be quite tired too as you will be up for nightfeeds and just keeping up with the extra washing at home (I'm using disposables but am still shocked by how much extra laundry my little one has created) can be quite a task and you will be doing this after you get home from work.

Then there's the noise factor. It would not work if you are working in a partitioned office. You would disturb others. Even if you could get your own office others would still hear the crying when it happens. If your job involves being on the phone your bubs crying would cause havoc to your day - they often cry when you pick up a phone.

You mentioned there were a number of pregnant women in the office. If they allow you to work like this they will then have to allow others to do the same. This could cause a lot of disruption in the office in general and I think there are very few employers who would be willing to allow it. There could also be health and safety issues.

My workplace has a work from home policy but in reality it just doesn't happen unless you are in senior management and even then it's for short periods of time - not a regular arrangement. Chances are your boss hasn't discussed the implications with HR and it wont turn out to be an option at all.

Better get going, bubs is a callin.
