there is no need to be embarrassed. It sounds l ike you are a deeply loving mother who wants and does the absolute best for her children. That is very special and the world needs more ppl with such a caring heart.
Take care.
p.s. about the boobs thing- my daughter (not yet 8) wants a baby in her tummy (becoz she loves babies so much!!) and boobs so she can feed it... I told her it wouldn't be happening- the pregnancy thing- for another 20 years at least lol.
