My son's lawn has a dip in the middle. The whole area is probably 60 ft

trying a quick fix by leveling with topsoil/sand/seed and hoping the
existing grass will grow through it. Is that a realistic expectation?

I read a long discussion about it on Gardenweb, so I know about sand
types etc, but what works in the southern USA might not be successful in
SE England. With a toddler charging about, doing a proper job isn't an
option for the foreseeable future .

Any advice welcome

What you don't tell us is the diameter of the dip

I won't really know the details till I get a straightedge on it.
Needless to say, it's not a uniform dip, but I reckon probably half the
area is too low by anything from 1" to 3"

I'd be inclined to remove the turf from the deepest part and add soil
then replace the turf, then later level with a top dressing of soil and
sand to get the final level.
alternative you could always lower the outside of the lawn
