Need advice on calories. Went from 1200 to 1400

Sdmommyof3

I am 38 5-3 180 pounds mother of 3 surro mommy of 3, two are twins. My daughters are 21,18 and 8 surro daughters are 4, 4 and 2. 4 c-sections later I am trying so hard to get this weight off. I have been heavy most of my life, heaviest being 204 at delivery. So my question is I have been on a 1200 calorie diet for a few weeks and going well. I haven't weighed myself yet but have noticed a small change in my body. I have read so much about how 1200 calories is bad so I just switched up my profile to 1400 calories. Should I notice a faster weight loss? Like I mentioned I don't have a problem with 1200 but I want to do this healthy! Any recommendations are greatly appreciated also on Monday I'm starting the 30 day shred, super excited!!
