Worried I will miss out on my grandson

Better to have the operation and be able to get back to full fitness than to worry about a 6 week gap in child care, surely.

You'll still be able to see your DGS .

Good luck with the operation.

6 weeks will fly by and you can be back to look after your much-loved grandson.
It’s better for your grandson to have a fit and pain-free grandma than an unfit one.
Good luck with the operation.

Can you adapt the way you care for him?

Shorter periods, by agreement with DD:

Sadly less cuddles and cuddle play, but a three year old is just about old enough to understand "grandma's shoulder is hurty". It wouldn't do him any harm a while to have ready prepared or mum prepared food - funny word games instead of physical games, made up stories, water play if its good weather, setting them targets..."I bet you can't run there and back quickly"

Is he potty trained? thats a bit of a "biggie"

Have your operation, you need it, your grandson will understand, at 3 years old, to be extra careful around you and can still give you a gentle hug without going near your shoulder. The 6 weeks will fly by. Good luck 💐.

Don't worry. Get the op. These are important life lessons for all concerned.

You already have that rapport, it won’t go away.
After caring for our grandson once every week from 1-3 years, we retired and moved 250 miles away. We see him 4 times a year or so, for a week each time, now, with a few flying weekend visits by us. He’s nearly six. When he arrives, it’s like we saw him yesterday. Don’t worry, the bond is lifelong 😊
