Appear to get Dad out of bed (3,2)
I believe the answer is:
pop up
'appear' is the definition.
(popping up is a kind of appearing)
'get dad out of bed' is the wordplay.
'get' says to put letters next to each other.
'dad' becomes 'pop' ('pop' can be a synonym of 'dad').
'out of bed' becomes 'up' ('up' can be a synonym of 'out of bed').
'pop' put next to 'up' is 'POP-UP'.
'to' is the link.
(Other definitions for pop up that I've seen before include "which may interrupt computer user" , "book for youngster" , "Appear (like toast?)" , "three-dimensional picture book" , "Appear suddenly or unexpectedly" .)
