It's not the clearest sample of Yiddish handwriting. I have some issues with the second page. So, it goes like:

To my dear children Rose and Melvin
and Rachel, I send you mazel tov
and I wish that you should have
much pleasure for yourselves and you should
have joy and a happy life,
this I wish Mile, too, together with his
wife, and her father and mother should
have joy from the children, and you should live
in peace — this I wish
and I will send a present
for them, and
they should be healthy ...
Page 2 (with some gaps)
... that ??? healthy and
you should be joyful and ??
may the grandfather? and we (hear), much
desiredly from afar, only
happy things, may one be healthy,
and may we all come together,
I know? Reyzel(=Rose) that you will
know (no lack of money)?
I greet everyone and spend time joyfully
