Dear Koni,
Before answering your questions I have a few myself.
Have you been trained as a paediatric physiotherapist in the Netherlands or are you still studying?
I know how we are trained in Holland.

What do you know about the general development of an infant?
What are the child's problems? Is he/she hypotoon or does he/she supper from general hyperlaxity of the joints?

What would your treatment goal be and why?
What is the parents goal for treatment?
Do you want the child to commence walking with shoes or without?
Did the child have shoes on with the assessment?

In general I can tell you that children that are a little hyperlax in the joints often walk in this manner.
Make sure the child is wearing good supporting shoes (tiny boots). This can make a huge difference.
In most cases a child will want to practice a new skill (such as walking).
If this is not the case I think assessment as to why not is important.

On this wonderful site you can find a lot of theoretical and practical information on generalized hyperlaxity, low tone and much more.

kind regards
