We are currently in an ice age so I presume that you actually are talking about glacial periods. But no. It's doubtful that we will see another glacial period that soon. Even without the "help" of the CO2 we are pumping into the atmosphere, it will be quite a lot longer.
We have a problem and while it will probably take about 1500 to 2000 years,
Most CO2 scenarios led to an exceptionally long interglacial from 5000 years before the present to 50,000 years from now, with the next glacial maximum in 100,000 years.
Changes in obliquity are one part of the conditions which are thought to lead to glaciation. There are also changes in the Earth's orbit itself which affect insolation. (see the same source)
This then correcting for the Wobble that results from not having such an object to correct what results in Ice ages on Earth

Definition: "A period of time in the Earth's history when ice sheets and glaciers advanced from polar regions to cover areas previously in a temperate climate. Several ice ages are evident in the geological record, the most recent ('The Ice Age') being from about 1 million years ago and lasting until about 10 000 years ago when the ice retreated to its present polar extent."

"The Ice Ages are generally seen as a time of glaciers, mainly because this is the Northern Hemisphere experience. In the Southern Hemisphere, the Ice Ages saw much smaller glaciers, and the main effect was for the weather to be cooler, and very much drier.
Nobody is really certain what causes an ice age to start, but one possibility is increased dust in the atmosphere, either from a volcano or from a large meteorite impact. This dust would then increase the world's albedo, cooling it down, and causing more snow and ice to form, increasing the earth's albedo still further.
The main problem with this theory is that we do not know what would then cause the Ice Age to finish. Maybe dead organic material, trapped under the ice, breaks down to form methane, or ocean currents switch, warming and melting the ice, or maybe it is something completely different.
What is an ice age? An ice age is a long interval of time (millions to tens of millions of years) when global temperatures are relatively cold and large areas of the Earth are covered by continental ice sheets and alpine glaciers. Within an ice age are multiple shorter-term periods of warmer temperatures when glaciers retreat (called interglacials or interglacial cycles) and colder temperatures when glaciers advance (called glacials or glacial cycles).

Between the 17th century and the late 19th century, the world went through a 'Little Ice Age', when temperatures were cool enough for significant glacier advances. This may have been caused by lower solar activity, or any of a range of other astronomical effects. Popular candidates for possible causes include slight changes in the earth's orbit, wobbles and precessions in the earth's spin, and maybe even the earth passing through clouds of stellar dust."

2.3 billion years ago things were very different. The Sun was not as hot. Days were shorter. But I don't think we had two Moons. Hard to say though.
However, by stabilizing our, rotation by re-creating conditions that, existed prior to 2300 million years ago would seem to make sense.
