I have parents who started with me on a regular schedule, same drop off time... then mom decided to work from home. Ever since then I get "XXX didn't really eat much" or " they just woke up" No structure at home! So I started saying "oh, ok well snack time is in an hour, I'm sure we'll be ok until then" ect. She got the point. Now she either feeds them or drops them closer to snack time. LOL Your client has given you an opportunity to respond. She said right in her email " I hope it's not a problem for you " It IS a problem. let her know, I feel snack at XXXX time. I do not supply breakfast. You have to put your foot down somewhere otherwise it's all over. She'll keep walking all over you. You're not the nanny, your the daycare. They are 2 very different things.
