I'm like 43cm and I don't think it's normal or natural.
Usually a big belly simply makes it difficult to lean forward, like having something big in front of you. (duh)
but at this size, I'm like leanign back halfway at all times, because even being up straight puts to much pressure on it.
has anyone ever REALLY tipped over?
Did it work? Maybe if I let myself fall forward, by trying to stand up straight, the baby will "pop out of my tummy" (using my 4 yr old's vocabulary, sorry.)
