3 girls within 4 yrs.

I have 3 daughters all born within 4 yrs. My oldest is 5. My middle one will be 4 on Wed, and my youngest will be 2 next month. So, you can probably guess that my sanity is long gone by now. Parenting is hard…almost too hard. I have been slacking in the discipline department since we have been in transition. I just can’t seem to get it together. I know what I need to do and what I should be doing, but I am extremely mentally, physically, and emotionally drained. How come I can’t snap out of it?!? I guess I am just having a down day. Sorry.
