Its driving me nuts!!

St

My 13 month old is going back and forth with 1 or 2 naps a day. We were doing so good at 1 nap and then he randomly passed out one morning and threw it off again. This has happened like 3 or 4 times where I think finally we have a routine again and then bam, thrown out the window! I'm so tired of the back and forth. I'm a SAHM and trying to get out of the house with this has not been easy, I'm going stir crazy! And hes a menace after he does this! For days! He sleeps through the night at least but I need a schedule back!
