Welcome home Hayley and baby Jacob.
That must have been really tough being away for him for 5 nights.
Isaac had to go to neo natal too and had all the drips etc, he had jaundice but they gave him fluids in case there was an underlying infection. Lots of blood tests etc. I know how worrying and upsetting that period is.
If Jacob is anything like Isaac, he will go from strength to strength now that he's home. Isaac is still really difficult to wind bless him.
Take lots of pics and post some up when you get a chance.
