First thing is not to over worry, I know it’s easier said than none.
my son had a lot of surgery as a child on his leg, and is facing another now as an adult. I know it was for a different condition, but I can help advise on preparing you and your baby for the hospital stay.
my nieces little girl had a cast fitted at 22 months, it was hard work simply because she was so heavy. So with that in mind make sure speak to the hospital/Red Cross about getting a suitable push chair for her.
if she’s not already, try and get her potty trained, it will be much easier for you and more comfortable for her.
you will need lots of suitable clothing, again the nurses are amazing at helping with that.
try and plan activities for her todo when sat still, though believe me, children soon learn to adapt and she will drag herself about if need be. I’ve seen child sat astride skate boards 😂
it will be hard, it will break your heart, it will push your patience to the limit, but believe me, it will be worth it. The times I’ve been in hospital with my son and seen so many children go through this, but it will be worth it xx
