My last child

Katt
I'm a mum to 7 and I'm pregnant with my 8th it's a little girl my last girl died at 6 weeks old, accident caused her to be taken away from me. I'm so scared that something will happen that I've put so much security around ie monitors sensor mat nothing around that could cause any danger. Is there anything I've missed?
