  We discuss the production of light nuclei in heavy ion collisions within a
multiple freezeout scenario. Thermal parameters extracted from the fits to the
observed hadron yields are used to predict the multiplicities of light nuclei.
Ratios of strange to non strange nuclei are found to be most sensitive to the
details of the chemical freezeout. The well known disagreement between data of
$^3_\Lambda\text{H/}^3\text{He}$ and
$\overline{^3_\Lambda\text{H/}^3\text{He}}$ at $\sqrt{s_{NN}}=200$ GeV and
models based on thermal as well as simple coalescence using a single chemical
freezeout surface goes away when we let the strange and non strange hadrons
freezeout at separate surfaces. At the LHC energy of $\sqrt{s_{NN}}=2700$ GeV,
multiple freezeout scenario within a thermal model provides a consistent
framework to describe the yields of all measured hadrons and nuclei.
