New small business

I just started a small side art business 2 years ago.  I’ve sold items but am not making a profit yet.  I have quite a few equipment expenses, some materials expenses, and also I’m taking a few classes to further my craft.  Questions I have are: 

1) What does the IRS consider a reasonable amount of time to claim losses before starting to make a profit?

2) things like laptop, phone, and iPad - can I claim the whole expense in one year or spread it out over time?  If so, how do I determine the amount of time to amortize?

thanks
