OK, confession time, me and my friends usually find the most INAPPROPRIATE cards to send to our other friends and some family on pourpose. A few months ago, I gave a very dear, very macho make friend a "To a sweet little princess on her 2nd B-day" card. He almost fell out of his chair laughing. My nephew does the same thing to me as I do for him, he gave me an Arbor Day card for my B-day last year...I did not even know they made Arbor Day Cards.
As for the Easter egg hunts and the lifesaver books. Yeah, it may be annoying, but if it is not hurting you, and it makes her happy, I say go ahead and do it, one day you may be sitting back and missing those times when your wacky mom made you hunt Easter eggs at age 47, 52, 60, 80... and the memory will make you smile, and you would do almost anything if you could only do it again.
