My MIL (who is wonderful) is providing our childcare currently. My husband is a key worker and works shifts, so our childcare requirement varies between mornings or afternoons, usually 3-5 times a week. She is very insistent on us using her and would be devastated if we put DD (18 months) in nursery. I have no issues with her childcare and DD adores her. Although she is very eager I feel like we are taking advantage. She won't take money and I present her with small gifts and bunches of flowers from DD. But how else can I show how much we appreciate her help?
