Returning to work with a BF 3mth old??

I am keen to get back to work. I haven't been back to work in my industry since having my DS1 in 2007 so I am starting to worry that I will be out of touch. The reason i haven't gone back is because it's very hard to find work on a part time basis. Today I was having a look on Seek as I often do and I found the perfect job for me, and it's with my old employer so I'm confident I would be able to get it, if I want to. The thing is I wasn't planning to go back to work until next year. I don't need to financialy but I feel like I need to exercise my brain before it turns to mush IYKWIM.

I told DH but he said it's way to soon maybe if DS2 was 6 months but he is not even 3mths yet (and I'm breast feeding). I really don't know what to do, the job advertised part time or job share and they are after a few people. I would make sure I was very honest and put on my cover letter what days I am prepared to work (2 days per week). I would also have to check if i could get DS2 into child care and increase DS1 to 2 days per week before applying.

I DON'T KNOW, Has anyone gone back to work with a bub this young??? The bonus is I have worked for them before so it wouldn't be like starting a new job, they would be flexible.

I don't want to miss an opportunity and then not be able to find work down the track or have to work for a company I don't know and have to start from scratch.

Sorry for the rant, I am so torn:wall:.
