Mom opinions needed!!

So, I’m a nanny/babysitter for a family that I’ve been with for 9 months. The past 6 months I’ve been ttc and it’s been tough. I was diagnosed with pcos and suffered two losses so far. The emotional toll of watching an infant is wrecking havoc I’m on me. I did not see this coming at all. Unfortunately I’ve decided to resign and I’ve accept a position at the company my husband works for. It’s an amazing opportunity. That being said, I’m giving the family a whole months notice (4 weeks) that I’m leaving, I’m going to offer to help as much as I can with finding childcare and I’m offering to cut my last weeks pay, since they’ll likely have to pay someone else, or put a deposit on a daycare. Is there anything else you can think of that will help soften the blow? I hate that I have to leave because I loooove this baby as my own, but it’s becoming too much. I never would have thought this would happen. If you have any suggestions on things I can do or say please help. I feel like garbage over this.
