Aww hun, hope your SIL and her LO will be ok. For a bit of reassurance tthough my cousin had pre-eclampsia and was induced at 24 weeks and LO was in NICU for months, then SCBU for longer but she took him home on Monday and he is a very healthy happy little boy. Rest assured that they do everything they can do ensure LOs are ok when they are born so early.
Really hope LO cooks alot longer though xxxxxx
