DS is 2 1/2. I work 3 days a week and on my 2 days at home I try to make sure we meet up with a friend on one of the days.
The other 3 days he is cared for by grandparents and goes to 1 playgroup (and park, shops etc)
So he has 2 definate social meetings a week (and will often also see his cousins or play with whoever is in the park too).
He does not go to nursery/ Pre school at the moment and won't till next April.
Is this enough or do you think he should be socialising more?
