I don't find it selfish at all. In fact probably the opposite.

You may find it's not easy going back that early. I went back at 7 months & I really wish I'd stayed home 12 months.

If you are like the average mum at 12 weeks you will be sleep deprived and adding work into that mix as well is going to make life tough for yourself.... no chance of having a nap under the desk at work.....that's why I say not selfish.

You will get comments from people but you may as well get used to it as TTC, pregnancy & being a mother opens up the flood gates to all sorts of comments from people.
