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"
