Baby changing bag! Any tips?

Kaela • Starting to try for a second baby after the birth of our beautiful daughter on 20th March 2016.
Finally got my baby changing bag! 
Can anyone give any tips on what i really need to put in it? Hoping I've got it covered with the following:
Wipes
Nappies 
Barrier cream
Muslin cloths 
Bibs
Spare vest
Changing mat
Nappy sacks
Antibacterial hand gel 
Breast pads
(I'll put my normal handbag stuff in there too I imagine)
Any advice appreciated!
