I planted a new lawn last fall which has come in nicely. Unfortunately,
one patch of maybe 15 sq meters is pretty infested
with what my wife has identified through some googling as
chickweed. Will regular mowing take care of this over time or
should I consider something more drastic?

Regular mowing should take care of common chickweed, but if you have
common mouse-ear chickweed mowing will not help. In this case you
will need to apply a lawn weedkiller to get the little beastie under
control. The leaf is very different on the two. Mouse-ear chickweed has a
hairy leaf.
Thanks for the help. Could you take a look at this picture and help
me with a positive ID?

I'm afraid it has hairy stems and leaves....

If I have to use a selective weedkiller, any advice on the tradeoff
between abusing a new-ish lawn (from seed 8 months ago) and letting
the infestation continue until it is the recommended 12 months old?

I'm no expert, but that ain't any kind of chickweed I've ever seen, mouse
eared or regular.
