4/5 engaged

It means baby’s head is just beginning to enter the pelvic brim. Basically 4/5ths of the baby’s head can still be felt above the pelvis so still a bit off. I was 4/5 at 36 weeks and I’m still the same today at 38+4 xx

It means babies head has only just started to enter the pelvis and 4/5ths is still palpable.

It doesn’t mean anything though some babies engage fully weeks before birth and others aren’t engaged even in labour x

Was just about to echo what Yasmin said. Typically I have read for second babies, they tend to engage in labour as opposed to before labour, so whilst the information may be interesting, it doesn't offer any real insight on your how quickly your LO will arrive xx
