Looking for friends to loose the extra fluff while I keep gaining the muscles!

Very active mom of 4 kids 3 years old and under. I keep control of my busy life and keep my sanity training 5 times a week. I need my sweat time. I decided to crank up the heat on my diet just 2-3 weeks ago as my twins are letting go the breast. They are 20 months old. I ate all the good stuff already, just no portion control as I wanted to keep my milk supply up. I still lost a lot of weight since they were born. Probably around 15-20#. I leaned down a lot while gaining an impressive amount of muscle mass(for me!). Anyhow, 2-3 weeks ago I weighted 156#. Now around 146-147#. I think my ideal weight would be around 130-135 as I am quite muscular and 5'2. I think I am loosing weight too fast. Trying IIFYM, I think I def need to up my calories. It's hard to pinpoint. Started with 1430. Just upped to 1633 yesterday. I'll keep playing around that. Any advice?
I mostly do short HIITs that involve a lot of lifting using the Keelo app and I love it. Around 325 WOs done since last fall. I love running and do it sometimes, but I am too busy these days to run regularly. Other than that, I am a part time lawyer, par time SAHM. If you think we have common interest, add me!!
