I can't decide...

I was offered a job by I Love Children recently. Now i'm confused... should i accept? It would really be a good experience, and I would really love to say yes! But the issue here is that I have to continue working after school reopens (perm part-timer). I have no idea how my schedule will be like. Would I be able to cope? Should I or should I not?? ? What do u think? I really need your comments... thanks in advance... =)
