How much do babies (less than 18 months) need to be socialised.

[Carsandtrucks]

Is nursery a couple of days a week enough? Obviously you wouldn't keep them in lock down on the other days but I am wondering if I should be making some kind of special effort.
Interested to know your thoughts

Mine don't even do that to be honest!

DS1 is two and DS2 is 16 weeks. Other than the odd group when DS1 was little I haven't really bothered with anything deliberate. We meet up with a friend and her little boy every week and go to swimming lessons once a week, occasionally go to softplay etc but other than that we don't do much at the moment.

Having said that, DS1 is lovely with other people - really friendly and smiley.
