Baby boy middle names

Jocelyn • I`m 27 and my husband and I have been TTC for baby #1 since October 2014. After 2 years of trying and 1 round of IVF we're finally pregnant
My husband and I have agreed on Colton and Caleb as possible boy names. I like Colton Wiatt (husband's middle name) but my hubby hates his middle name. Do you have any other suggestions? Also would like suggestions for a middle name for Caleb as well. Thank you!
