Help: tip toes or flat feet?

[GingerCuddleMonster]

DS has a activity centre that has a raised floor, that is sprung which allows him to bounce, this can be altered in height. It's suspended via bungee cord from the three legs.

My question is, should he be flat footed or on tip toes? it didn't state in the instructions .

DS is 25weeks this Thursday.

Somewhere in-between I think. Tiptoes is not good for them, and completely flat footed is I think potentially bad, they can land too heavily.

I really don't know, ds walks up me when held under his armpits, I don't know what to do, I'm not sure if he should be trying to walk yet.

Inbetween sounds good, I don't leave him in there longer than 20mins on and off throughout the day. He has floor time but gets frustrated as he wants to crawl!

he's driving me insane
